4.3.4 Jamba only working when not in party.

Hi, my name is Herman, I run 5 ele shammys. They are lvl 60 atm. I have never had a working jamba and only just discovered it works perfectly as long as my master is not in the party.
I am only using bartender and tried disabling it. Still the same problem. All my toons are in the same communications channel with the same password.

AS mentioned in the title i play on a private server (4.3.4 cata). I have no idea why jamba is behaving this way. I love the addon as long as it works. :O

Thanks for any help I might get!
