Reply to Pitch Faders

When in traktor pro with a vci 100 firmware 1.3 and arcade mode, My pitch faders do not stay accurate with the screen now. When I move the pitch fader all the way up or down the screen only moves the fader about half from center in the program. Tried to reset nothing. Also tried to reload and nothing. What can be the problem. It does not stop me from playing just would like it to read correctly.
