Address field validation

I have made a form that uses an Address field. I have successfully set up the Google Maps API key in the form settings area and I have also selected the 'Allow form submission only if data source variables in the Label control are resolved.' option as "YES"

However, in my form, submitters are able to submit the form by entering non-valid address values in this Address field such as "Hello123". The form field does not seem to validate whether or not a proper address has been resolved in the lookup and accepts the value. The non-valid address value does not populate the Address object variable outputs (e.g. street number, locality, formatted address, etc.) as it is not a valid address.
