Reply to KeyRig 25 Button Mapping

So, I've got my KeyRig 25 all mapped out for Traktor, everything's working great, EXCEPT that I can't figure out how to map the buttons. I'm trying to get a delay freeze button going. The knobs and the actual keys work great, but the buttons aren't popping up when I activate Learn in Traktor's mapping window. I've tried resetting the controller and reloading factory settings from Enigma, but nothing's working. Any suggestions?

Cheers!
