DC F-14 and X52 Throttle issues

I hvae some issues with my Logitech x52 throttle and the F-14. I cannot pull back to zero Throttle, it sticks around 20%. And it moves not really smooth to 100%. And sometimes it jitters heavily. I only have this issue with the F14 in combination with the X52. The x52 works fine throughout the entire Sim and with any other aircraft. The Logitech Yoke Quadrant works fine with the F14…

Any ideas? Thanks.

Its actually bugged right now. After you use it the first time it does that every flight. A fix is on the way I believe.
