Lightroom classic photos are reverting to original settings

There have been a few reports in this forum of LrC edits reverting to previous values by itself. I don’t know if there has been a solution found, but you might want to search this forum for those other reports. Adding a few minutes later: the search here in the Adobe forums is useless, but something called Google finds such posts, such as this, which actually has a possible solution.

Another thought is to reset your preferences file.

I agree with ​@RobbyJai that this definitely has nothing to do with the capability of the hardware. Even if the hardware was much lower speed and less capable, this should not be happening.

First of all how are you changing edits?
You are not touching sliders so I guess you are using -/+ to edit the the parameter (likely this)

In any case seems simply the photo was not ready.
 

1. You navigate to a photo (photo has Exposure + 1.56)

2. Immediately started to edit it and bump exposure, bezel appears.

LrC reverts to the table of edits when you just “opened” the photo.


You can likely solve this by waiting a few tenths of second before you start editing.

This will give UI time to be fully drawn, edits be loaded, preview rendered.
 

Hello,

I have also been using Lightroom for 14 years, but since version 15.4.1, I have been experiencing several issues with features that had previously been working properly.

My equipment and system are as follows:

• Fujifilm GFX100S II

• Canon EOS R3

• MacBook Pro M1 Max, 64 GB RAM

Here are the issues I am currently experiencing:

1. Develop settings reverting to previous or default values
   As mentioned earlier, the adjustment settings I have applied sometimes unexpectedly revert to their original or default values, either during editing or afterward.

2. Tethering problems with Canon cameras
   When using my Canon EOS R3 for tethered shooting, I experience several problems that did not occur in previous versions of Lightroom.

3. AF control conflict between Lightroom and the camera
   When I control AF from the laptop, AF does not work properly on the camera itself. This creates a conflict between AF control from Lightroom and AF operation on the camera.

4. RAW files being saved as JPEG files during tethered shooting
   During tethered shooting, some files that should be saved as RAW are instead saved as if they were JPEG files.

   In some cases, the file has a .CR extension, but its actual file size is identical to the corresponding JPEG file. Lightroom also recognizes these files as JPEGs rather than normal RAW files.

What is particularly frustrating is that new problems seem to appear with every Lightroom update.

Because of these issues, I have currently had to downgrade Lightroom to version 15.3.1. With version 15.3.1, these problems do not occur in my workflow, and Lightroom is relatively stable.

I have been using Lightroom professionally for 14 years, so I am very familiar with its normal behavior and workflow. These issues did not occur in my previous working environment. They started appearing after updating to the newer versions of Lightroom.

Sometimes when you work with external hd or internal sata discs, the xmp-files does not get updated. It's simply too slow. I then go to the library tab, click the thumbnail view, mark all, right click and choose metadata -> save metadata to files. It takes an eternity but that fixed that problem for me. 

I have created two smart galleries that detects when the catalog and hd is out of sync. It happens often. First time I did this I had 14000+ images out of sync. They all exhibited strange behaviours after editing. Usually the exclamation mark in the thumbnail down in the time line indicates a sync problem, but far from always. 

And while syncing, I recommend not editing. It will create further stress towards the disc, which is the why the problems show up in the first place... 

There is a lightroom bug which is driving me up the F'ing wall. in a nut shell

1. i shoot a wedding

2. dump the photos into an edit folder

3. run Aftershoot over the top of it which does my cull and pre edit with a set specific way i edit photos. it does all the straightening etc etc

4. I then import all the photos into LR and build standard previews.

5. From that i then go through each image and edit everything the way i want.

Thats my process.

There is a bug thats driving me up the wall. Its random and i cannot find a specific reason why it does this. Essentially I adjust the photos exposure if i need to ... and randomly some photos will accept the exposure adjustments and then others will just revert back to the original setting prior to adjustments.

Its batshit crazy and i cannot work it out and its driving me up the wall. Reinstalled LR and still same problem. Thought maybe it was aftershoot and xmp files. But nup.. happens even when i edit directly from the original files that have never been ingested into LR. Have attached video.

Pay attention to the exposure slider. Anyone else experience this and know what it is?? you can see it happen twice in this short video. where i adjust nothing but the exposure some it will accept happily others it just reverts back to original   → Video of it happening

In Development History, I see entries after the last edit of the following kind (from bottom to top)

From Lr mobile

Multiple settings

Camera Raw settings.

Items in the History Panel appear because the user performed some action (perhaps accidentally and thus the user is not aware of this action) that caused something to happen and be recorded in History. I'm not aware of any other explanation for items to appear in the History Panel. I've never heard of a bug that does this. I don't know what actions will cause these items to appear in the History (except for the first one, which seems pretty easy to understand)

Please check recent backup copies of you catalog to see if you can find an earlier version that doesn't have these items in the History Panel.

Hi @jans90185495,

Thanks for the detailed explanation. I understand how worrying this is, especially with a large catalog. To help narrow down whether this is catalog-specific or app-related, could you please try the following:

• Update Lightroom Classic to version 15.1 and observe if the behavior continues.

• If you have a recent catalog backup, create a new empty catalog and import that backup into it, then check if edits still revert.

• As a quick test, create a brand-new catalog, import a few test images, apply edits, close and reopen Lightroom, and see if the edits stick. This helps confirm whether the issue lies with the catalog or the application.

• After updating to 15.1, please copy and paste your System Info (Help > System Info) into your reply.

These steps should give us a clear starting point to investigate further.

Thanks for your patience, and we’ll take it from there once we have the results.

Best regards,

Anshul Saini
