WiFi Connection Strangeness

So I just got my Fenix 5x, and want to connect it to my home WiFi network.

I didn't finish doing so using Garmin Express, and will do it. But before I did, I attempted to connect using just the Fenix itself.

When I click on Settings/WiFi/Connect to Wi-Fi, it displays:

Searching for Wi-Fi Network...
Transferring
Transfer Complete

... however, I never set it up with any WiFi network.

What is it DOING there? Is it finding whatever open WiFi channel it can? Because it doesn't let me select one...
