I need help, I managed to get the elevator out of the c8m4_interior map, but there is an invisible wall that prevents me from passing, I want to remove that invisible wall so I can place a staircase. Can anyone help me remove those invisible walls?
Elevator

With this eliminate the elevator in case you are interested.
