Album list not appearing in MPDroid

First all, this is my first post and so far it has been a pleasure running Mopidy (on pi musicbox).

I have a nas drive with 12,000 music files.
Mopidy seems to handle them ok, a little slow. But that is to be expected.

The Artist and Album list appear fine in Mopidy, but when i try and view them in MPDroid only the artist list is returned. The rest provides “no results”.

I recognize this could be a MPDroid issue. But has anybody come across this before. Do you know of any limitations to the number of artists / albums that can be transferred over and MPD server?

Many thanks,
