Jerky motion on contoured moves

I have setup a countoured moves but when it reach the final point there is a fast jerky move forward and then backward that is not acceptable for my application. I'm using a 7344 and a 7356 (the same behaviour) motion controller and i have already tried to change pid and everything else. The only way to get a smooth movement is to return to the initial position (let's say 1000 steps forward and 1000 steps backward). In this case no jerky motion is done. But this is not acceptable for the application i'm developing. I have the latest firmware and sdk 6.1.3.
I really need to solve this issue. Can Someone from NI help me?
