Edit this Albumartist and take a look at the ‘Sort Artist’ field.
You have set the primary metadata agent of your library to Personal Media. This agent can only fetch album cover art from your files, but no ‘artist’ pictures.
This rogue album art might still be there, but in ‘hidden’ files or even in files which are marked as ‘system’ so you even have to activate another checkbox in Windows to be able to see them!

I urgently recommend you to use a folder structure like this:
/Music
/Artist Name 1
/Album Title 1
01. Track Artist - Track Title.mp3
02. Track Artist - Track Title.mp3
03. Track Artist - Track Title.mp3
...
/Album Title 2
01. Track Artist - Track Title.mp3
...
...
Name it folder.jpg and you can make it bigger than 500px for better quality on those fullscreen Plex apps.
Always a good idea!
They are not, as soon as you have a ‘sampler’ album or ‘guest musicians’.
Then you need the Album Artist to keep the album together. Otherwise it will get split up into several albums – one for each differing Track Artist.
If you are changing embedded meta tags, your changes will in many cases only appear in Plex after you have performed the Plex Dance.
