Number Formatter Localize setting not working


I am working through the CarLot program and I cannot get the US Dollar symbol to show up in the program when I add a new car. It shows a weird looking box symbol instead. I have Localize checked in the Number Formatter for the Price and my system settings are for US Dollar ($).

Also, If I completely delete everything in the price field and type in a number, nothing shows up when I hit return.

(I am using Xcode 5.0.2 on Mac OS X.9)
