Shared Groups - Groups Disappearing

Hi, anyone having problems with groups disappearing?

I’m using Openfire 3.9.1, this version is working fine, any version above i have this kind of problem, the groups persist in disappear every time for every user.

I created a shared list with my groups in my console, so every user when he/she is connected with Spark can see that many groups. The first minutes or hours, every works like a charm, after some time this problem starts.

I haven’t seen such problem with latest versions. Maybe this is a client issue? Do groups disappear in console also or does sharing option gets disabled on them?
