Try moving around your lights maybe? Perhaps what's happening is that your lights are setup in a way where they is nothing to reflect and so you don't get that feedback and nice reflections. Also maybe make sure your Color Attribute Node that is sourcing from "mask" that it's written exactly as the source. And maybe even check the mask itself, since perhaps is making everything transparent.

Just in case, also double-check your Vertex Colors.
