Strange Black Shadows on Landscape Material

Hello Unreal community,

I seem to have run into a very strange issue that is causing incorrect black shadowing to occur on my landscape.

I created my landscape material using Megascans textures and followed this tutorial by Lukas on YouTube: Landscape Material Tutorial Part 1 (Unreal Engine 4) - YouTube

I know its not being created by the lighting because even if I disable my environment lights and through a light right next to one of the ‘shadows’ its still there.

If I disable the tessellation on my material, its fixing the shadowing issue but I would like to have the tessellation enabled.

Any ideas as to what may be causing this to happen?
