Macros and Hotbar

I just noticed that when you create a new Macro, it won't go into the 2nd hot bar, it will fill just fill a space in the first one. It's kinda hard to explain but give it a try. Fill up Hotbar 10 and leave Hotbar 11 (below) empty, do a macro and the Macro won't go into hotbar 11.

the top hotbar is the main one, it's the reason why there isn't any set commands to activate abilities on the bottom hotbar and probably the reason why you can't get macro's there on there from when you press enter.
