Reply to play button glitch? or traktor?

hey! i just got an s4 yesterday (it is amazing), i was playing around, and seemingly all of a sudden, the right deck's play button wouldn't play the track that was loaded. instead it made the on screen pitch slider move all the way to the top, and the phase meter was panning back and forth. i notice this effect also happens if you press down on the jogwheel while a track is playing. i am trying to figure out if this is a hardware glitch, where the jogwheel might have been "stuck" down, or if i acidentally re-mapped the play button to have the effect of pressing the jogwheel... does this make sense? please help, i hope my stuff isn't faulty! i'm a total beginner at traktor btw so i could easily be doing something stupid. thanks!
