I struggle with CD’s from a Box Set. In a few cases, I have tried to merge individual discs into the original box setup. Often I succeeded. But in some cases, Roon combines the CD’s into the proper box, but leaves separate albums alive but with no tracks. However, if I trying to delete these albums, there are a few louse tracks, which are not visible in the album view. Given that I am very scared with the delete button, these albums are still around. How do I get rid of these empty/not so empty albums
