Our Calendar Event asks for zip code upon registering. We found that if a constituent already exists in the system with completed address information, the registration seems to be overwriting all of the address fields with blank values except for zip code. Is there a way to prevent the other address fields from updating with blank values?
The address fields assume that the full address will be obtained in the event registration. If you have to include 1 address field, then you'll need to also include the other address fields, street 1, city, state and zip.
