I’ve moved the post to the correct forum. 

Sorry I am on the wrong side. Don’t now how to delete the post

Problem with Lightroom is resetting my edits. When I open Lightroom again some of my photos edits are changed back to the original. Very annoying. The Xmp file is in the folder but its half the size from those where my edits are left in Lightroom.

Questions about Lightroom (not Lightroom Classic) belong in the Lightroom (Ecosystem) forum, and not in this forum (which is the Lightroom Classic forum)
