Default location

This looks like a great plugin.
However I can’t seem to get the default location to update. I enter the longitude and latitude and then tried clicking “Edit Settings” (which seems like odd wording if that’s used to save the settings) and I’ve also tried simply entering the info and clicking to another page.
Neither option seems to make a difference.
Am I missing something.
