Multiple level objects loading

When I launch selected viewport objects from other level is loading into it (Player start, lights, tilemap, and objects like door in example screenshot)
But It’s only happening in that level. In other levels it doesnt happen (altho I’m not sure. Currently got only 2 lvls)
