If you are working on multiple variants of similar images, like with focus stacking, and have layers added to perform local adjustments, I have noticed an odd glitch.
Namely, if you copy and paste your adjustments from one to another, then make an adjustment to the initial variant only to copy and paste the adjustments again, the local adjustment layers are doubled. In all of the variants you applied to, you will end up with the original layers added in the first "copy & apply" plus those same layers again, or any additional layers you may have added, even if you did not make any changes to any layers.
Is there a fix for this?
