Applicants are not able to edit or delete reference requests if they have been finalized. However, you are able to move the reference letter or request to your the Archived tab of the Document Tracking section, effectively removing it from your Current documents. This tool is typically useful if you do not wish to use a particular document towards any programs during the current match year.

If you wish to later restore it, proceed to the "Archived Documents" tab, locate the document from the list and then click on the backwards click icon to put it back into your "Current Documents" tab.
