Plex Displays Random Wrong Combined Artist Names

Folder organization.
Music / AlbumArtist / AlbumTitle / Tracks

All albums, with all their tracks inside a certain “Album Artist” folder must be tagged with the same album artist name.
If there is even only one track with a wrong or missing album artist tag inside there, it can set off all other albums.
Find that deviating track(s).

I’m assuming that you have both albums with “SonReal” and “SonReal & Rich Kidd” tagged as AlbumArtist inside the same albumartist folder.
