Landscape material layer won't update

Hi everyone, so I have this issue and Google refuses to yield relevant results.

My problem is my landscape material layer #5 will update the landscape, UE will compile the shaders, but then it refuses to render. I can sculpt the area, delete the layer info and try again, nothing works. It’s stuck on the default texture when I paint.

Even if I paint in a new landscape block, it will compile the shaders again but stay stuck on the default texture.

Any help would be greatly appreciated! Thank you!!!
