It seems that when you include Saint or Mount / Mountain in the city name, it does not properly understand what the city is. Take the two examples:
111 Example Name Mount Pleasant SC 11111
111 Example Name St. Augustine SC 11111
In the first example, the City will be Pleasant and the "Mount" will be part of the street. In the second example, the "Augustine" will be the city and the "St." will be part of the street. If you convert "St." to Saint" it works great.
