To edit the Referral Source from an existing application, you must first remove the existing Referral Source, then set the new Referral Source:
1. From within the application, on the Overview page, scroll to the bottom.
2. Within the Metadata section, click View details:
3. You will then see a pop up with the option to remove the existing referral source from the application. Click REMOVE:
4. You will now be able to add a new referral source to this application.
Important: If you are adding a brand new referral source you have not yet added in your list of referrals, you can still add it by simply typing the name in the pop up field and clicking on the "Create New Company:..." button.
