Known issue: Email templates not available for selection for document delivery emails

Issue

This issue can surface when one or more templates in the system are configured with a data context of Task or Prepare Document.

Resolution

To resolve this issue:

1. Find all email templates that need to be available for document delivery emails by browsing to: Launchpad > Open Documents Admin > Document Templates > Email Templates. Then, perform the following steps for each template. 
2. Override the default display context and ensure that both the data context and the Prepare Document type are set, for example: 
   
3. Ensure that Display rules and Legacy Display rules are not enabled. 
   

After performing these steps, the correct set of templates will load in the dropdown.
