When in the Edit Addresses pop-up, the system will allow you to delete multiple addresses (essentially cleaning up the whole record's address history) only to tell you when you try to save all those changes that "One or more of the removed addresses belong to a relationship and cannot be deleted." It doesn't save ANY of your changes after that. You have no choice but to Cancel, losing ALL the changes made. Either make this error message appear at the time that specific address is deleted or change the functionality to delete ALL BUT that one address when you save changes. Screenshot attached.
