Your folder organization needs changing. Always stick to
/Music <-- Plex music library points here
/Albumartist
/Albumtitle
01 - trackartist - tracktitle.ext
02 - trackartist - tracktitle.ext
03 - trackartist - tracktitle.ext
I see you have an arbitrary folder level by “date” in there, which might confuse Plex.
The above folder structure is also needed for compilations. The only difference is that Albumartist = “Various Artists”.
ALL tracks within the folder Various Artists must be tagged with identical Albumartist = “Various Artists”.
This is doubly true if you tick “Prefer local meta tags”.
If there is only one track in there with a deviating albumartist, it might change the albumartist match for all albums inside that folder.
Double check your folder structure and the embedded meta tags. Then perform the Plex Dance with all albums inside of Various Artists.
