Raid Party Frame

[galladriall]

Hi guys,

I am having a problem with my raid party frame. For some reason my NUI for some reason will not show anything higher then 10 man.
If I am in a 25 man or 40 man raid stiff bickies I can't see you unless I open the Bliz list and thats poo

Can anyone please tell me how to fix this? I am sure it is simple but I am at a loss.

Thanks very much!!
