Screwed up artist names

[nic1]

Hello there!

This is my first post although I read with interest here in the past.
MinimServer is a cool application.
I still go with the 'Starter' edition on my DS218+ since I upgraded to MinimServer 2 but now it behaves strange in combination with my music collection. (I had a bit of a struggle at upgrading so I'm glad that it does work again at all.)

My problem is: The displayed artist name on my media player (Yamaha NP-S303) isn't the title's "artist name" tag as before and expected, but it's always the "album artist" or the "composer" of the track. Sounds a bit weird but this even happens when I go over the "items" list. Album artist. Don't know why ...
As far as I remember, this worked without a problem at MinimServer 0.8. But because I only have the free version, I cannot reset the configuration easily.

What can I do to see the the real "artist name" (like it's called in foobar2000 for example) for each track on my MinimServer again?

Thank you in advance,

Nico
