FWBA - No Left Turn?

I was flying my wing today (running pixhawk and APM Plane 3.6.0) and I noticed that in FBWA mode I couldnt turn LEFT.
Right turn was working. I switched to stabilise and I could turn left and right no problem.

Can anyone read BIN logs and work out what my issue is? On the ground, I moved the sticks and the wing, and everything was moving as you would expect
