Tempo and play/pause won't work on U-Mix.

Since we have upgraded to 1.7.1 Cross on the MacBook pro, we've upgraded the new software onto the iPad app U-Mix Control, everything seems to work fine except; Cue, play/pause, tempo and sync. We are on Dual Stereo and everything seems to work fine except for those settings, but if I manually do it on my decks, the displays will come up on the app just normally.
Are there any settings we must change or check to make sure it is working properly? Thanks for help.
