Bouncing procedrual meshes

In a game I’m making I’m trying to let you slice tress so they fall down. However whenever I create a procedural mesh(I have followed many guides on how to do the slicing of meshes) and start the game the meshes bounce which than causes to trees and any other static mesh Ive tried to fall over. They also bounce whenever i try to cut them, Has this happened to anyone else? Anyone know any solutions?

Bounce as in you need to adjust your physics settings?

When I started the simulation they flew into the air. Howevor I managed to find a solution, I accidentally crashed my game and when I turned it back on I of course lost some stuff and than when I redid them they no longer bounce. This was my 5th time doing the same thing again so I dont know what I did wrong every time but I got it to work.
