We assume a folder represent an album (or disc of an album) and this section lists folder where songs in the folder are matched to different MusicBrainz release, usually all songs in a folder should be matched to the same release.
We can select an item to look in more detail, so here we can clearly see that Disc 2 , Track 11 has been matched to a different (Incorrect) album. This can be fixed using Match To One Album task.to force all songs to the same release.
