Missing album cover

[bmjmb]

I have an album downloaded (Rise Against - Appeal to Reason) and the album art doesn't show up. It also doesn't show up when I'm in the album on the artist's page, but it does on the list of albums. I've tried deleting the album and re-downloading, un-saving and re-saving the album, but it's still not there. If I go from one album to this one, it will show the previous album's cover will show. I have a LG Google Nexus 5x Running Android 6 Marshmallow. I have no idea what else to do.
