Location Manager: Set Cookie?

I am playing around with the locatiom manager for a new project. I thought the location switcher was supposed to set a cookie that would follow the user through browser sessions.

In playing around with my staging site, the location switcher resets to “In:Everywhere” with each page load.

Meaning, if the user sets their location to “Philadelphia” and navigates to /url.com/contact, then the location switcher will reset to “In:Everywhere” instead of storing their location.

Is something broken? Or am I misunderstanding how this is supposed to work?
