Need urgent help regarding controls!

[Khaziir Everflight]

I got a bit of an issue... I got a Thrustmaster Warthog Hotas and the Turtle Beach velocity one rudder, but every time i jaw with the rudder, the throttle gets set to zero, which just is causing me all sorts of headache... anyone got an idea what the issue might be?

Already checked that the throttle isn't overlapping with any axis of the rudders aswell, so i am thoroughly frustrated and confused.
