MEP 7000 Left Player- Tempo isn't working correctly

The left player tempo only goes up/down .1. Or .01 when I move it. I have changed the tempo controls and it doesnt change anything. I can move it on Serato with the mouse but the moment I touch the tempo lever it reverts back. I have reloaded the MEP software and the same thing. I can adjust the speed using the jog wheel but not the slider. It seemed to happen after I upgraded to the newest Serato. The right player works fine.
