How to permanenlty delete rendlnsts?

When I try to remove rendlnsts with the rendlnst tool they keep coming back after restarting the mod. Is there any way to remove them permanently? (I’m referring to already placed buildings, objects, etc…)

scene_remover. But you should keep it where it is.

Did you remove thousands of them or just dozen? When I removed them with Remove button and saved my map they were removed permanently and never showed after map restart in editor.
