Tracker yaws in opposite direction to quad

Hi,
I was field testing the antenna tracker AT1.1. The tracker yaws in opposite direction to the travel of the quad.
The “reverse” check boxes for both yaw and pitch are inactive in the Extended Tuning page in MP.
I seem to remember they are active in the previous version.
Can the developers or anybody help ? Is this the proper way to reverse the yawing ?
The FC is Pixhack 2.8.4.
Thank you.

set servo1_reverse to 1 from 0 or from 1 to 0

Thanks, Dick. It seems working in SITL bench testing.

Will do field test over weekend.
