World Composition Landscape black

Not sure why but I have a black area which is somehow part of the landscape but the landscape doesn’t go that far. I did have a landscape area there but I removed it since I was adding land on the wrong sub level. I have 1 persistent and 2 sub levels at the moment but I don’t want to add land now on the 2nd sub level in-case of further inconveniences. There are no other landscapes.

Something added outside of the level bounds to one of the levels will cause this to happen.

Thank you, I checked 1 of the assets was just clipping the edge causing the issue. Everything is fine now.
