Header navigation different in admin portal

Using the Canvas theme, I have set the login/signup buttons to be in mobile menu (only on mobile) like this:

This is exactly how I want it to look.

On the website (BLOOM, the Nav (and the logo) are not changing to the mobile version when resizing the browser. This is pretty much a stock install of Canvas so wondering what I am missing?

I think something that was not supposed to be changed, was changed in the editor.

In my app, the responsive design works (when you change the browser width lower enough it changes from buttons to hamburger icon).

Seems to be working fine for me (or have you fixed it now?)
