Track/Album composer link

When I search Beethoven in composers I would like to know how to un-link these two albums from Beethoven.
Alicia Keys - Songs In A Minor and Chuck Berry - the Great Twenty Eight (contains song Roll Over Beethoven)
How is this done? I can’t find any composer field in Album or Track Editor

Did you ever figure this out @Robert_Jackson? You should be able to remove the composer credit in the track editor, under Credits.
