Google Contacts in iTunes not updating correctly

We've discovered a problem when using iTunes on a Windows computer to add Google contacts to the Contacts app on an iPad. Once you use the Configure... button to load the contacts from a Google gmail account you can't use the Configure... button again. We've even tried uninstalling iTunes, then reinstalling it. The contacts are saved somewhere on the Windows system and iTunes just keeps using the original gmail contacts rather than allowing a new set of Google gmail contacts from another Google gmail account to be used.
