Jive roster groups ERROR 501

Ok here is my problem

I manualy add people to a couple different roster groups. For some reason only the first group shows up.

This works for some time, but after a couple hours I try to relogin and i get this from my jabber client…

…and neos hangs there as “Connecting”. I think this is related to the groups that I created, but am not sure. When i delete the roster groups that created, everything works fine again.

What am i doing wrong.
