Whats wrong with my Landscape

I having an issue with my Landscape.
I have my real ground landscape shadowed by a “ghost” landscape. When i disable/enable nanite, the ghost landscape is visible. All my map and foliages are builded under the real ground, making impossible to continue whith that “ghost” landscape as definitive.

Is there any type of cache that i can clear for landscape or nenite?

Anyone know whats wrong?
