This issue can be caused by the address of the user being in the system without the City field.

A Platform Manager can navigate to:
  1. Core.
  2. People Finder.
  3. Search/select the user.
  4. Click Contact Card.
  5. Scroll down to Address.
  6. Add the City.
  7. Save & Exit.
Once the address has been updated for the user, an Admissions Manager will need to go to:
  1. Enrollment Management
  2. People Finder
  3. Search/select the Candidate
  4. Click the Checklist tab
  5. Scroll to the bottom of the Checklist tab to Applications
  6. Delete the Application.
Once removed, the family can re-complete the Application Form, with the City saving since it's been updated in their user record.
