Destruction meshes keep floating, doesn't fall down

Hi there.

I made a destructable mesh, and I have a problem, that the destruction mesh keeps floating and doesn’t fall down. The mesh keeps floating in air, rolling, or gets launched somewhere don’t know where.

I want the mesh to fall down, like being pulled down by gravity, just being attracted to the ground. I messed with settings like gravity, mass, and those two Linear and Angular Damping. Help me please. Any informations you need to know I will provide.

Thank you.
