Unable to set County in Dynamics Nav Using the Web Service

I am working on integrating our e-commerce system with dynamics nav on the backend. I create a customer if it doesn’t yet exist. All of the fields seem to stick EXCEPT for ‘County.’ When I do a Read on an existing customer, County is filled in with the correct data.

Oddly enough, when I create the sales order, neither Ship_To_County, Bill_To_County nor Sell_To_County seem to stick there either.
