Hi,
Even if it display "USA" as default, you have to re-save it in order to be sure that the right value is stored in the database.
If the default value (stored in the database) is not published, the list won't display it so another value will be displayed, but won't be the "default" or the "real selected" value.
But more than that, which version number of HikaShop are you using ?
There was a bug in a previous HikaShop version, fixed in the latest build.
