Improper Library Labelling & Metadata in Music

Now I have discovered another problem. Every time I scan the Music Library to have it discover the newly added albums while attempting the “Plex Dance” method of library management, it seems to remove a previously added and recognized album. This is so buggy and there is no reason I can think of why it would remove a previously included Album from the library. It is still present in the Music Folder, it has not been deleted and it was previously seen and recognized by Plex.
