SERVO_AUTO_TRIM both ailerons up

Hi all,

After a long time of trimming new planes manually and then using the TRIM_AUTO param, I decided to give the SERVO_AUTO_TRIM a try. The outcome is a bit puzzling, since after the flight, both ailerons were pointing upwards in neutral trim (see picture).
Here is the procedure I used:

1. Launch the aircraft in MANUAL
2. Change to AUTO on a ~500x300 m square at 200 m
3. Change SERVO_AUTO_TRIM to 1
4. Let the aircraft fly 5-6 rounds of the mission
5. Switch to MANUAL
6. Land manually

It’s maybe important to note that we set up crow flaps as here (swapping the two output channels and setting the channel reversal as needed). Log is attached.

Does anyone know what went wrong here? I suspect there is a problem with my parameters, but I can’t figure it out.
