Employee Self Service Emergency Contact Phone is added to wrong Who's Who Line

We're testing employee self service to allow employee's to add emergency contacts but we've run into an issue. When the employee adds an emergency contact and the record is moved from the work tables to the live tables, the emergency contact is added to say who's who line id 4 but the phone number is associated to who's who line id 1.

Has anyone run into this? Is there a workaround?

Thank you
