Opaque grey windows

I am using an Autodesk family for the windows in my project, Window-Double-Hung. None of the materials that are applied to this family show up in Enscape, so everything is grey and opaque. Is there a way to solve this issue?

Confirm materials are applied to the window and also that phasing is set to show complete and not overridden.

Thanks, @phil_read ! Sorry for the delayed response. I spoke to a fellow Enscape user who suggested the phasing setting, which solved the issue.
