Issues when limiting Locations

I’m trying to limit the areas where my product will be sent. However, when I added and activated a new Location, I’m still getting the huge long list of places from the States dialog box. Under Locations, I literally only have the one state listed, so why is there 50 in the drop down box for the shipping address on the registration page? :confused:

When registering, the States/Providences info is utilized, however upon checkout THAT’S when the customer is alerted that there is no shipping to their area.
