They are scenery elements, so you have to put normal paths on top of them. The idea is that in SMBX you can place a path on top of scenery, which makes it so that the specific scenery object disappears when a path going through it is unlocked, like in Super Mario World for the SNES. While you won't be able to see them in the editor after doing so, they will still be in the world map file and will appear in-game.
It's a pain, but it works.
