Two Navmeshes Mesh Issues. How to change the default navmesh?

I am creating a point and click game. In it, I have a first story and second story with a ladder in between. I am currently teleporting the character using the ladder use to the second level, that works. However I have a problem.

When I tried to put two navmeshes, one for the ground floor and one for the 2nd floor, as soon as I went to the second floor, I couldn't get it to work as the navmesh was not active I guess.

However, I thought I could avoid this by making a very big navmesh that combined both the first and second floor and putting a hole in the middle of the navmesh so the player couldn't reach the second floor as there was a hole. However, the player can still 'travel' through the sides of the hole, even if I overlap the hole over the navmesh. As such, the player flys up to the 2nd level.

Is there a way to change the active navmesh either using variables or action Lists?

You can use the Engine: Change scene setting Action to change the active NavMesh.

What's your Pathfinding method set to, at the top of the Scene Manager?
