FYI:

  1. If we refill the value in the edit in full page view. we can save the form.
  2. If we save the form from the quick entry view the form will get saved.
  3. If we make the Skills Required field not Mandatory, the Skills Required pre-filled data will get saved in the edit in full page view.
