Control surface results in inverted aerodynamic effect

The pitch control surfaces of my airplane have an inverted effect. The control surfaces are at the back of the plane, clearly behind the center of mass and the center of lift is behind the center of mass so the airplane is stable. When the pitch control surface is rotated upwards then the plane pitches down, and vice versa, while it should be the other way around.

The screenshot shows the airplane, I can't show the actual problem with only a screenshot. The problem occurs both in the air and on the runway. When the pitch control surface is rotated upwards on the runway, the wheels squeek because the plane is pushed against the runway, when the surface is pitched down there is no squeeking and the plane lifts off.

I tried to fix this by trying the following changes but they all didn't make a difference:
- Remove the roll control surfaces such that only the pitch control surfaces remains on the wings.
- Flip the wing 180 degrees over two axes and then reattach on the other side such that up and down are switched.
- Switch the 'InvertAirfoil' option of the complete wing on or off.
- Switch the option 'inverted' of the individual control surface on or off.
- Switch the control surface input between auto and pitch.
- Launch vertically (with small SRB's attached for liftoff) or horizontally.
- Set configuration to rocket or airplane.
- Fly (with vertical ascent) on a mission or fly without doing a mission.
