Thanks for adding me @mseaton, I wasn't watching this closely enough!
Mike correct, the issue is that we are not passing in information to the navigator model as to how to render the name... we should pass this in via a "display-template" attribute, and create that template based on the address template.
The display template is set up in the navigator model here:
Unfortunately, the display-template is not at all documented nor easy to figure out. I'd need to do a little work to figure it out. I'm willing to work on it, but probably won't get to it for at least a couple days... if no one else want to take it on,let me know and I'll pick it up.
