UNREAL 4 - Character ejected 50 meters in the air, when jumping to a destructible mesh, why?

Hi, every time my character jumps over a destructible mesh, when it explodes, sends my character to the air…. like 100 meters in the air… how can i keep my destructible mesh exploting when character jumps over or touch it, but avoid destructible mesh to send it into the air when it explodes?

Thanks
