not all albums under artist appear in database

[micrometer]

I copied artist, album, title... into rockbox (ipod 6) just fine. I "initialize now" the DB after the copy. When I open database > artist and see the albums, many are not showing. I went to Foobar 2000 to quickly see the DB by artist, album... and I can see all of the albums by artist on my ipod. On the ipod, I can even select by database > album and they are there and can be played.

My question is how can I get all albums by artist to show in database > artist?

Thanks,
Mike
