Terrain Turning Black in editor


I have a scene with a number of terrain squares. When I open up Unity, over half of the terrains are black. I have not gone into play mode with this scene yet. I’ve done a good amount of research on this and have had no success. I am using Unity 2019.1.11f1. Restarting Unity doesn’t do any good. I am building for PC/Linux. Anybody got any ideas? I’m kinda stumped and can’t continue until this is solved.

Thanks in advance!

Maybe try messing around with the terrain settings? I’m really not sure but I recall having a similar problem and solving it by changing things up until I found something that worked.

I have tried messing with the ones that aren’t the ones absolutely necessary, and have gotten nowhere. Any other suggestions?
