Unable to sort non-iTunes library on server

I maintain two music libraries. One iTunes library for iOS devices (AAC files). One home music library for home audio system (FLAC files). Both are on home server. Fidelia recognizes both libraries. However it can only sort iTunes library, but not non-iTunes FLAC library on server. This completely defeats its usefulness managing library.

UPDATE:

uninstalling and reinstalling Fidelia solved the problem. Updated to 5 stars.
