UE4.19 - Destructible Damage Spread Broken

After spending some time playing with the destructible meshes in UE4.19, I think the damage spread setting is broken. Please check the gif in the link. I’ve tried playing with all the settings, adding asset support by locking some chunks or adding world support using some static meshes, but I can’t get the behavior where only the hit chunk is set free, the whole mesh will always collapse…

Any help appreciated!
