RoutingVia design rules: Via "Template Preferred" not showing Via Templates

[smoothVTer]

I have a project to which I've added a PCB document, a schematic document, and a pad/via templates library document:


The pad/via template library is part of the project, as you can see the red arrow above highlights.

There are 2 vias in that library:


And the defined vias appear in the Vias templates panel:


However, when I try to define a PCB Design Rule using the "Template Preferred" Routing Vias, the fields are unpopulated:


 There doesn't seem to be a way for me to select the Pad/Via templates library I have already defined and added to the project.   What am I missing here? Is there a bug in Altium or am I missing a key step?  I've read the online documentation and it leads me to a dead end.

Seems to work for me on the latest version.
