Modelling of volume pile

Good Morning Sir,

I am modelling my concrete using volume element in PLAXIS 3D. It is easier to get shear force and bending moment through this modelling. We can get the bending moment and shear force along the length of pile using cross section curve or center line which can be detected automatically. But in my case the bending moment and shear force are shown for a fraction of length of the pile. I am not sure what is the reason behind it. I need your help to resolve this problem. For better understanding I am attaching the Screenshot of the thing.
