HELP - CDJ's Jog Wheel plays previous track instead of staying at 0:00

Hey everyone! Hopefully one of you can help me. So the other day I was DJing off of CDJ 2000's and any time I moved the jog wheel past the start point of a track (0:00) it would go into the previous track.

(Before I sound crazy, the only time I move the jog wheel past the starting point is when I try to scratch in a new song, do a spin-back or search for a start point.)

I never had this problem before, usually when I'm on CDJ's and I move the jog wheel all the way back it just stays on the same track and won't go past the 0 mark. Is there a way that I can fix this, so the jog wheel won't act as a track search button?
