Docking System @ Schiphol

I have Cloud9's AMS scenery and while all other airplanes work with the active docking system, for some reason the 737-800 will not work, the -700 works fine as well all other POSKY aircraft. The only real problem that I can see is that for some reason the -800 does not sit on the ground properly, the wheels are sunk slightly, yet on the -700 it is fine, it sits perfectly. With both aircraft they are using the realistic gear points (Which I like the feel of better) Now I know with these gear points the aircraft may not sit perfectly which is fine for me, but the -700 sits fine and works with the gate system and the -800 does not. Can anyone help me out here?
