Every album_artist is the same.
I can skip the Plex Dance by renaming the album (remove one letter for example), saving, and then restoring the album name. This also shows that Plex does recognize the album, and fetches correct metadata. The name is also the same as shown in the screenshot (there is no extra spaces, or any special characters).
However, this still does not fix the issue of Plex making multiple albums for a single entry.
I have also forgotten to mention, that these albums were already in the library before, and got split later on when I added something else (doesn’t matter what, another artist, another album, another track). So basically these albums split on scans.
