Auditags are not extracted very well

Hello,

currently I have small problems with my audiofiles.
ffmpeg -i shows the following:A
=====================================
Input #0, flac, from 'Dance.flac':
Metadata:
ALBUM : Waterloo
ARTIST : ABBA
GENRE : Oldies
TITLE : Dance (While The Music Still Goes On)
track : 6
=====================================

If I access serviio audio database from the path:
Audio -> Album Artist ->
Result: u -> unkown -> Waterloo (Album) -> Title of the track
As think I get the wrong result. In my minds it should be:
Result: Abba/Waterloo/Tracks

Any Idea?

Artist and Album artist are 2 different fields.
