Vista - WLM 9 Beta: Inconsistent Behaviour in number of contacts in catego

Next to the categorie name, there is a number between parentheses.
Unfortunately there seems to be some problem with them.

I've detected 3 modes of operation in MSN:
1. Shows the total of contacts in the category.
2. Shows 0 (happens only when there are no online contacts)
3. Shows no number.

In the latest, closing and opening the category usually fixes the problem.

If I remember correctly, in the previous version it also showed the contacts
online by using a #/total notation. I guess that this would be the preferred
method and would like to know why was it remove from the beta. (It only
behaves like that on favorites).

PS: I know you probably already know :P But I still like to write it down to
have a measure for myself.
