experiment on. Use mp3tag to get rid of any tags that are not ID3v2.3.
There are good instructions in the wiki and on the mp3tag site for
this.  Then rescan and see if it shows up.  This is basically what you
need to do, eliminate any possible tag conflicts.  Mp3tag is free and a
very important program to fix tags and do much more.  Ape tags sometimes
take over preference in programs and sometimes they have very little
info.  If you use mp3gain to do your replay gain this could be the
problem.  It writes the replay gain tags to v2.4 so a lot of programs
only see the replaygain tags and not the album artist, etc. that are
written to the ID3v2.3 or the id3.1 tags that contain all that stuff.
I've see it happen a lot.  Mp3tag will show you all the types of tags
that you have in a album and let you get rid of the ones you don't
need. This is what I would recommend starting with to find the reason. 
It's not that hard and once you find what is causing it, if it is tags,
you can then fix your whole library quite easily.
