1. Add a new user record for the parent

2. Remove the parent relationship from the candidate:
  1. Go to Core > Users > Edit User Profile Data.
  2. Search for and click on the name of the candidate to enter the candidate's profile.
  3. In the Relationships channel under Parent(s), the candidate appears as a parent because the merge replaced the parent with the candidate and made the candidate a parent to themselves. Click Delete next to the candidate's name to remove the parent role.
  4. Click Confirm.
