FX In CFX POst

I've started to simulate a UAV on CFX.
We need to get the Cd (Drag Coeficient) throug a alpha polar.
The issue is that for some angle of attack the Fx (normal) over the model is positive, and for other angles of attack (the higest), the Fx normal is negative.
The 0,0,0 coordinates is in the midle of aircraft.
do you know why we have this change on the Force.
The Pre are exactly the same, the only difference is the angle of attack (V*sin(alpha))
