DJX XZ pad selection bottoms on deck 2 not working

On deck 2 in stand alone mode when I try and choose a different pad mode, the different pad function cannot be selected. It is stuck on the hot cue. If I hold hot cue down it then jumps to the beat jump option being selected. Then randomly it will go crazy and all pad call buttons flash on and off. Then it will get stuck on beat loop?? Can you help
