On one msn account it works fne, i can see whos deleted and not but on the other account i cant see that, very weird. i can see when people was last online but it says that everone on the list has delleted (and they havent).
Does anyone know why it works on one account but not the other?

Apparently there's been a few issues with the Windows Live contact servers recently. I'd just leave it a while and see what happens. (Although you may wish to clear out your temporary contacts directory for banter, search around for how to do this...)

Edit: See this thread.

It's definitely nothing to do with WLM, WLComm or any contacts cache, as I get exactly the same info on aMSN on my Mac as well on my PC, both of which are showing inaccurate reverse lists.  The problem exists with the data not being received from the WLM Servers properly
