Abaqus dynamic explicit contact issue

I'm trying to conduct a drop test analysis in abaqus where i have modeled a freely falling body as rigid with given mass  under gravity, the deformable body is to be analyzed as body inclines and falls on it but while viewing results it is observed that deformable body develop stress prior coming in contact with rigid, and stress is develped without contact. Please let me know how to solve this issue.

model notes:

A common general contact with penalty and normal "hard contact" behaviour in all bodies is appllied in dynamic step.

Dynamic Explicit Analysis step.

Only 1 deformable body in model.
