On most orders since 3.5 update and recent Yak updates, most United States orders are defaulting to "AB" (Alberta, Canada) for the state field when the order is processed. It will show the correct city and country but the state is wrong. On the front end, state drop down is normal and correct state can be selected. It's when the order is placed that the state will usually change to "AB". Not every order, but most, and no real rhyme or reason.
