States do not display clearly on the store location screen. Need to add some margin below the dropdown. Also, need to limit states to those belonging to the country selected.

There is still a slight issue with an extra gap of styling at the bottom of the CP. But this is related to Craft core CP styling.

At the moment it doesn't cause any breaking issues, so will look at it in the future.
