tags albums unitserve

hello,

i have a little problem: i want to tag some albums i have downloaded on my naim unitserve, because the photos of a few albums are missing.

i go to the naim desktop client on my pc, the unitserve ( nssr) is selected. I see the tittles: albums-artists... but when i click on albums or titles, nothing appear: i can't see my albums which are on my unitserve. Have i forgot something to do?  thanks
