Onhit on cube falling from sky

Hey there.
I have come by a situation i dont understand. Im fairly new to unreal engine.
If i drop a cube from the sky and it falls and hit the ground(physics and gravity enabled).
The OnComponentHit(StaticMeshComponent) get called, but it get called for like 40 times or so. This happens even tho the cube dont “leave” the ground.
With simulate and frame skip it dont seem like it “leave” the ground but onhit get called so many times. There is no bounce.
Would appreciate help
