Able Ability System Info and Support Thread

I am trying to create a binding for the branch ability. when I hit the plus button to create a new binding, it creates a new function “OnGetDyanamicProperty_Ability”. it doesnt seem to set the next branch ability at all. http://prntscr.com/nbw01c this doesnt work for some reason.
edit: I realize after reading the rest of the posts i should wait for the update to hit first.
