Weird problem selecting Genre etc.

I'm running twonky on a readynas. 99% of the time I go into twonky from n stream and select album artists and everything works fine. Today I thought I would browse by genre, and it gave me a list of albums. Selecting albums gave me a list of something else. 

If I select genre on the unitiqutes front panel using the remote, that's whaeverything. Plugplayer also works fine when selecting genre etc so I don't think it's the upnp server. 

Anyone noticed anything strange with n stream?
