P: Point curve settings are missing when creating a preset

@Arjun Lall  Thank you for confirming!

Thank you! I can confirm this now works as expected.

This is still happening as of Lightroom 7.0 Desktop, no matter what I do my curve settings don't save to any profiles I create or update. However, on my iPad it works fine.

BTW I hadn't updated my lightroom two months ago when I saved my preset. The wrong logic was likely introduced shortly before Amani Ali created this post.

HI I have the exactly same issue for LR, not classic, on both Windows 11 and MacOS Sonoma. It is not OS related and I believe it is related to how the program saves the preset.

If one exports the preset and use any text editor to look into the xmp file, you will see how this is defined.

For example, this is the Parametric Curve adjustment I have for one of my preset, which is saved a two months ago when this feature was still working.

If we look into the xmp file, we will see all of the points defined as they are. Each of the tags defines one point in the curve.

But If I try to save the preset using the latest version of lightroom with a post-editing image, and then export it, I can only get two tags in the xmp file. 0,0 and 255,255, which means no info is saved.

However if I try to use an existing working preset, like the one I demonstrated above, and then copy all of my settings back, and then save the preset again, I will get a working preset with curve info.

My theory is, there might be some logic issue in preset saving for the new lightroom version. If I change the settings for a image in the new version and save it to preset, it won't contain any curve info. But If I apply an old preset, and then modify and save it to a new one, it creates a new one following the old preset logic, which makes it work. The is likely caused by the logic in how new Lightroom version saves preset from scratch.

BTW I am pretty sure the preset I created two months ago containing curve info, so the wrong logic was likely introduced in one of the newer versions after that.

Adobe please take a further look at this issue and solve it for us. This is causing some trouble for my photo editing, and I am just an amateur. No ones knows if any professional photographers is affected by this issue and it might cause a much more serious trouble for them. Thanks.

@Adam28289253kj33for me it always works from mobile devices. but cannot find a way to make it work from a computer.

I found a workaround by updating the desired preset on Lightroom mobile via my phone. After a few attempts it finally syncs up and my preset saves the tone curve. Agree this is a new bug, never had this issue beforehand. 

@Cihad Aydın this did not work for me either:

You can also try choosing "modified" option. That also works for me.
