Scratching Problem Since Latest Update 2.7.8

I’m having a problem with scratching since the latest update 2.7.8 I’m using iPad 2 and the Numark iDjpro controller. I have never had this problem before, it only started after the update. It I have a track paused and I move the jog wheel it will not scratch. It starts searching thru the track even though I have scratching engaged not the search feature. It will only do this at the beginning of a track for about 6-10 seconds in then it starts scratching like it supposed to. Please let me know how I can fix this. Thanks
