Throttles at idle vibrating into reverse

[MediumRareBaku]

I am using the Honeycomb Bravo.

I've calibrated my throttles in the EFB. Idle calibrated to idle, etc., but no matter how many times I calibrate them, once my Bravo levers are at idle, the throttles in the sim sit there and vibrate between idle and the beginning of the reverse range, and sometimes vibrate enough into reverse that the reversers unlock.

I do not have any reverse bindings set in the sim and I do not have reverse on the axis set to on.

I am not using the 0-100 axis option per the manual.
