freelander 2 n/s front window

Hi all im after a bit of advice...I have a 57 plate freelander 2 and the n/s passenger front window doesn't seem to know when to stop anymore...if I use the one touch switch it will do up but will not cut out when it reaches the top and comes back down!!...I am able to do it right up by timing it correctly using manual switch.my question is do I need to change the switch or is there a cut out sensor so the window knows when to stop???

Sounds like it needs recalibration

Instructions in owners manual

Or there is something stuck in the track, but calibration should sort it
