I had heard something about this. The idea is that you should be able to basically balance an airplane (front to back) at a point on the fuselage around the center of the main wings. If they moved that point farther forward, it almost suggests the plane needed the addition of a canard wing to compensate.
Trying to save money to avoid all the testing, etc. by making it a different airplane, they may have pushed the “modifications to an existing airframe” envelope too far on this one.
If they moved that point farther forward = farther BACKWARD.
i.e. it sounds like the plane is nose heavy, and the programming may not have accounted for it properly.
