Incorrect Servo activation when switching to Auto

I have a 3 position switch on a Turnigy 9x set up for Manual/Stabilised/Auto on a fixed wing aircraft running a 2.6 Arduplane with the latest software.
Servo response on Manual and Stabilised is correct however as soon as I switch to Auto the right aileron servo moves about 20% of its travel to drop the aileron.
How can I prevent this?


Drop one aileron or drop one and raise the other?

Because it’s going into a navigation mode it’s actually in the process of navigating so don’t expect it to have the aileron level when switching to Auto, if they’re level in FBW_A mode then all is well (and they correct for roll in FBW_A)
