Huzzah! What made it work?

I have 4 pillars, with 4 ramps surrounding a platform. So I had to make sure the player can't go through these pillars.

I added walls and made them NON-walkable. The walkmesh has 2O materials you can choose from: Dirt, Stone, Metal... Water.

It was because of this NON-walk material I had this odd behaviour. I switched the walls back to Metal and only minor correction on some edges did the trick.

But I did everything step by step, to see when and where I got faults in...

Perhaps creating a tutorial alongside your current project will help others wishing to accomplish the same goal.
