Question:

Why a newly added role does not appear in a Vault document's Sharing Settings?

Answer:

This issue lies within the custom role definition. To resolve this problem, do the following:

1. Navigate to the affected Document Lifecycle.
2. Click on Roles.
3. Locate the affected role.
4. Enable the Add Default User When Creating a document checkbox.
   
   

If users hover over this option, the tool-tip gives more detail on the setting, which is to default this role into the Sharing Settings upon document creation. Ensure all changes are saved.
