When I search for a city that is in multiple states, the search list drops down with all the cities. You can't tell which state it's in. I tested Roseville which is in multiple states, and it lists 7 or 8. When you pick one, it shows what state it's from. You have no idea by picking though.
It should have the city with the state in parenthesis:
Roseville (CA)
Roseville (PA)
Roseville (WY)
That way you can pick the correct one. It happens on any theme. I have attached a screenshot.
