MS Master Materials not exporting to unreal with textures

Hello, when I export my textures to Unreal 4.27, I'm not getting the master material coming through with the textures, and there is no isntance of the material created. 

My Megascans logo at the top of the header is not green as well, I noticed, it's all white.

Can someone please help me figure out why this is happening? Thank you. And please dont say "send us a log", I never get a reply back after I do that...
