Cannot edit/correct a Carlos Kleiber Die Fledermaus highlights album

Weird. I locate an album with a different cover and all correct tracks, SAVE, but it does not change, despite preferring Roon data.

The entry that appears unmoved does not identify the tracks fully but the one Roon found does, yet “Save” does not save it!! Am I doing something wrong? This procedure has worked before but not on this album.

I finally fixed it but had to import the cover and edit for changes to the track. But I still cannot understand why, when Roon correctly identified the cover and tracks, :save: did nix.
