P: Desktop: Creating Duplicates Upon Saving

Mojave 10.14.6

This might be useful, thanks. But it happened to me when exporting whole year (not albums, but selection by date) and without deleting anything during the process, I was actually AFK during export.

anecdotally: It seems to happen specifically when I delete an already exported photo.

For example, I deleted a photo I exported with the batch by mistake, and then the entire export process froze and it started exporting multiple duplicates over and over and over.

I was able to repeat this multiple times.

ALSO seems to happen if I am exporting multiple "albums" at the same time.

Didn't delete anything during the export process and it seemed to work. Who knows.

Me too. God, as if CC couldn't get any worse/more inconvenient.

Is this their worst product in the current suite? I think so.

Thanks for the additional report. Make sure everyone is hitting the Me Too Button at the top of the page also. 

I'm also experiencing this issue.

• macOS Catalina 10.15.4 on a MacBook Pro (Retina, Mid 2012)
• Adobe Photoshop Lightroom 3.2.1, Build 20200403-1047-0e59df2

Anecdotally, it appears that the duplicates are occurring because the export task restarts for some reason. That is, I see the export task progress bar go back to the beginning, and it restarts exporting files from the beginning with filenames suffixed with "-2" (and then later "-3", "-4", etc if it restarts multiple times) to avoid a collision. For me, this seems to happen mostly with larger export jobs (anecdotally, I found that ~100 images exported as 90% JPEGs generally complete with issues, but if I try 200+ it will restart at least once). I have found that large jobs do sometimes complete if allowed to restart frequently enough (I had a ~300 image export job that ran to completion, but appeared to have restarted 8 times as the most duplicated photos had a '-7' suffix). I'm not sure if the larger jobs cause the restarts to happen more frequently, or if just by being a larger job it's more likely to restart before reaching completion.

Mojave 10.14.6

MacOS Version: 10.15.3 (19D76)

Same issue. It is eating up my time and resources. It is a major problem as I do lot of timelapse work.

Adobe Lightroom CC using desktop install 3.2. When exporting more than 10 photos at a time, multiple duplicate photos are created at random, causing the export to run for an extended period of time, and never completing. This is huge bug that has rendered the program useless. Previously I was able to export without this issue. Using Macbook Pro. I shut down the computer and changed folders without any luck. Please help. 

 Hi Rikk,

I have the same problem on my 2013 MacBook Pro:

* macOS Catalina 10.15.2

* Lightroom build 20200204-0604-bc5e360

Whenever I try to export raw images from my Canon M50 to jpg, the export gets stuck and starts over, which results in multiple copies of the image. I never had the patience to wait more than 8 hours, which was not enough to export 200 images.

I found the following workaround though:

Deactivate wifi to disconnect Lr from the cloud. Import the images, make your edits, and then export. Then, the export works like a charm. However, as soon as Lr had a connection to the internet, it does not work any more for those images and the export gets stuck.

I noticed that the export also works for photos that are fully uploaded to the cloud already. So I suspect this bug is related to the simultaneous upload and export of images (which is kind of the usual case when you import a lot of images, edit them and directly want to export them).

Hope this helps in finding the bug and fixing it.
