Reply to Key Control issues

Ok, so I'm attempting to map a key control knob to my omnicontrol, and for some reason the knob assigned to key, when turned, doesnt respond in traktor pro. It'll turn a bit but it keeps resetting back to the 12 o clock position on the screen and doesn't actually do anything to the key because it basically refuses to budge other than a little bit before it snaps back.

Does anybody have an idea as to why this would be happening and how to fix it?
