Why are the artwork all wrong?
I guess all these files are in the same folder. If you run ‘Local Artwork Correct’ which is a task in the default Autocorrecter it looks for image files in the same folder as the songs. Because it is very common for an album to be stored in a single folder with its artwork.
If this is the case delete the fields, then if you have already corrected the tags from Musicbrainz you can try and correct the cover art remotely using Update tags from Musicbrainz or Update Tags From Discogs.
