AddressFinder as whole has been flawed since there isn't a built in option for how to deal with the 'no valid address' checkbox.  At least in database view the 'USPS Nixie' codes get appended to the address attribute along with a date - so simple global changes post-AddressFinder will check/uncheck the no valid address checkbox accordingly.  With the automated NXT AddressFinder in it's current state - the address attributes don't get applied - so there's no way to mark no valid address when applicable, or unmark that checkbox globally when using the NXT platform.  We won't be using this function until it's refined to do what the database view function does.
