DDJ-RX Jog Wheel

 Just updated to Rekordbox 5.1.1 and now I'm having a problem with one (just one) of the jog wheels on my DDJ-RX. The right hand one works fine,  but the left one now only changes the pitch, rather than letting me search through the track. Both settings look to be exactly the same for both decks, so no idea one is working fine and the other isn't?
