Negative diagonal stiffness properties of curved beam

I saw similar questions but I am not sure that they are the same. I had some difficulties while modelling curved beam. Some of the diagonal stiffness properties  of the section becomes negative after solving with VABS. The geometry that we are trying to model is the following; 

 

-          Hollow tube

-          Ro = 0.0375m

-          Ri = 0.0325m

-          Material: Aluminum

-          Radius of the beam curve is 0.275m

-          90degree arc
