Reply to cross fader acting weird

whats up guys

i never really noticed this coz i never use the cross fader but i have recently..

when ever i go full right or left or close to it.. traktors cross fader starts to go to left and right heaps fast without me doing anything.. this has nothing to do with vibrations either.. and i have tried the cruve control at the back as well

does this happen to anyone else? i need it to work now since i am doing it all internally now

i have the ranking s vci100se.. got it december
