PCG Runtime Grass issue.

I’m working in UE5.8.3 using the PCG RuntimeGrass. I’ve done this multiple times before. Should be simple enough right? Wrong… Somehow Epic manages to break something else in a new version release. I can’t find anything on this. I’ve never run into this before. And I’m using the same material, assets I’ve used before. I have no understanding as to what is going on. I have no clue how to fix it. Does anyone have any idea what this is? And what is causing it? I’ve not had anything like this in previous version of Unreal.
