First Person Controller touching terrain causes teleportation

I made a Simple terrain, put some grass arround, some trees, some water and modeled it a bit, but when I place a First Person Character Controller, from the standart assets, on the terrain, whenever it touches the terrain on play mode, it gets teleported to one of the edges of the terrain.

There if I try to jump back on the terrain it keeps teleporting me out to the edge whenever I touch the terrain.

I haven’t found any solution.

I had problems with the first person controller simply delete the controller and add a new one.
