When I press the pause button, and then seek, I find that the position does not stop when I seek the position of the position, but go back, as to what is not necessarily, sometimes more sometimes less

The problem also appeared on when I put a pre-roll, I found that player position turns into 2 seconds, sometimes is 1 second.Is not what I want in the zero position

I was so sad,help me
