My LMS is running real nice (on a DS-412+). However, I noticed I'm missing some Artist. Not that they're not scanned rightly, but they show up in weird places. For instance Genesis and Deep Purple are missing in the Artist List under their respective letters (G and D).

I did manage to find them, though. They're hidden under V (Various?). However, their tags (as seen in LMS) show:

I'm not sure where LMS gets the WM tags from, as the files only have ID3v2.3.0 tags. Even removing the tags and rebuilding them doesn't change a bit. I even have some directories without tags as test, but they don't show up in the right place as well. It feels I've tried just about everything.

Any clues?
