Landscape turns black in new level only when I sculpt

Hi all. New to Unreal. I am using Unreal 5.3 using a downloaded Fab asset, the Medieval Village Megascans. When I am in their created level I can sculpt and paint with no issue. When I create my own level in their project, I can paint just fine but when I sculpt, the elevated terrain turns black. I am using RVT and enabling nanite. I am using their MI_Landscape and enabling each layer. What step am I missing
