Modelling Cables in SAP2000

I have a bi-convex cable beam modelled in two ways; In the first case, each cable is manually drawn after the curvature has been defined, while the second cable beam beam was modelled using the SAP2000 cable form. The same loads and target forces have been applied to both beams. After analysis, I'm getting the same forces and reactions in both beams but I'm getting really different deflections. Does anyone know why?

I have attached pictures of the cable axial force, deflection and reactions results.
