I'm having trouble getting my albums to group up together. I have checked the spelling of the artist, album, and album artist yet some of my artists are not grouping. The majority is working fine, it's just a few bands i am having trouble with for some reason. For example the band "Corrosion of Conformity" the album "Deliverance" There are 12 songs, broken up into groups of 1, 3, 1, 1, 1, 1, 2, 1. I've removed all info and artwork except for the song names. The artist and album are all identical. thanks in advance for help.
