problems with Artist.displayFormat

[Alhifi]

I have reinstalled the version 2.1-0600, activated the licence again and also installed minimstreamer ... after the rescan with the exact same configuration and of course music files it's still the same, only the composer is shown ...

Then I deinstalled licence and version 2.1-0600 and did a new install with the package which was listed within the DSM package center, it's version 2.0.18-1005 and did not install the minimserver just to check ... but it's still the same, new scan, after restart only composer is shown, no combination of artist and composer (this time again tested with Roku Soundbridge).

So what's different between the old 0.8.5.3, which as you see above works really fine, and the newer 2.x versions ... ?!
