Validating error that references "EngineResources"

I am unable to locate the exact issue with these files in regard to the EngineResource/Black file. It does not seem to be present anywhere in these Material Instances. I don’t see any references in the MI itself and I am not finding any references to the file in the Parent Material from within the MI.

Any help or education on this subject would be greatly appreciated. @ohmygrace
