problem: I can create a catagory as an admin, however I cannot allocate one to an epic. This seems to effect the "group by catagory" function with nothing showing below any catagories other than uncatagorised. This feels like its not working the way it was intended?

Any advice how we can get it to work so that we can view epics organised under the catagories?
