ILS approach help Freeport, Bahama Int. Airport

Hi all, first of I'm a noob here and have been playing FSX for about a month. I've got down navigation pretty well and have a good feel for small jets like the CRJ-700. I usually fly around the Dallas/Ft. Worth area but decided to try and fly more scenic routes. I flew from Miami Int. to Freeport, Bahama Int (I forgot the airport code and can't look it up since I'm at work). Anyway, my ATC directs me to runway 6 that is ILS capable. The ILS freq. is 109.70 heading 065. Ok to the problem, every airport I fly to lines me up dead center and then I'm good to land, at this airport I'm always to the right of the runway and have to manually correct. What gives? Any help is appreciated in advance.
