Hi Aaron,
I ran into something similar with layout templates not updating on the Home Workspace — sometimes it helps to reset the workspace cache manually or reassign the user role temporarily and then revert. That usually forces a UI refresh.
Unrelated, but while working on a tile design catalog layout recently, I found this guide really useful in explaining the difference between sanded and unsanded grout for a section on material specs:
