Group window quick cast button problem

[nexus37]

Cannot edit my spells for the group quick cast buttons. I bring up the Group & Raid button setting to get to the edit window but instead of the edit window it brings up the POI edit window. Everything worked fine before the last UI update, I un-installed the old Drum's UI before I installed the new one.

also - once I bring up the Group and Raid button setting window I cannot close it, the Save button is grey'd out.

need solution please ..

Thanks
