Landscape material troubles

I recently started working in UE4 & after watching multiple videos on youtube about making landscape materials I’m still having problems getting them to work properly. If I add a single material to my landscape the shadows look normal. If I add a multi-texture landscape material my shadows are pure black blobs. It has to be something with the material that I’m missing.
