Hi, using latest version of roon Sept 2021, Nucleus, meridian 218 and 52oo dip. I have about 1000 albums . My library and versions and tracks is kind of screwed up from bad edits. Is there anyway to undo all your edits anD return to original state? Also i seem to be having issues with merge and album collections. I make the right selections per instructions but all the covers remain in sight in the library after the merge?
