If you are running a y-harness for the ailerons to the aileron port and another y-harness for the flaps to the flaps port, then you don't need a "2 Aileron-2 Flaps" wing type. I run this same setup on my Cub and I just have it set on "1 Aileron-1 Flap" because I am using the y harness to bring the two servos into 1 port. Change your wing type to "1 Aileron-1 Flap" and I think you'll have better success.
