Annoying Arch+Design ME

[Streetwise]

I've had this annoyance after upgrading to 2016 (I think). Even after reseting Material Editor Slots, I no longer get the multi color VRay materials, but rather all MR materials. How do I change this back to display blank VRay materials?

3dsMax Customize menu
Custom UI and default switcher, then pick vray
Next reset shall reset with good stuff in there

BOOM!

Thanks so much.
