EDL Templates are not generated for a Study Site when the associated Milestone is created in Vault.
The Full Document Type field is not populated on the EDL Item Template that is used to generate the affected EDL Template.
The solution is to go into the affected EDL Item Template and populate the Full Document Type field with the proper values and save the changes. The user needs to re-create the EDL Templates on the affected Site in order to correct this issue on that Site.
