Bravo Throttle Quadrant Jumping

Please add the msfs-2020 or msfs-2024 tag to your post, depending on which sim your post is about.

The throttles worked perfect until a week ago, when I slide the first throttle handel ( 4 engine config ) up, just a little, the throttle jumpes to about 70% in the game. The other levers work still perfect. Then I tried MSFS 2020, it workes perfect. Checked the calibration in Windows = perfect. So it is not the hardware. Has somebody any idea how to correct this ( Boeing 747-400 ) .

I have the same.
Throttle Axis works perfect.
Throttle 1 Axis registers no sim movement until the physical lever is about 50% of the travel and then the lever in sim jumps to 50%
Throttle 1 (0-100%) jumps to about half as soon as the physical lever is moved up.

This used to work before. Please fix it. I am having to use just one lever with all aircraft to be able to manage the throttles.
