Problem with create graphs in runtime?

Hello. Im using v 4.2.17. I need help with creating an additional graph in runtime. I need to add and remove objects that the player and the NPC should walk on. I tried to do everything as in the documentation. Added a component GraphUpdateScene to the object, set the necessary settings (penalty or tag). When I turn the component on while playing, the mesh appears, but when I turn it off it doesn’t go away. And also, if I use a grid graph, then the penalties that I set in the settings are applied correctly, but on a Recast Graph, the penalties are not applied. That is, if I set walkability false, the enemy can still walk.

I make video with this problem. Pls help me to solve it. https://drive.google.com/file/d/1ihpY5CsWimOrZ9Tb6_FerUczqjTH1Rgd/view?usp=share_link
