Question:

Why is there no Stop using shared field button for the CRM Territory Field in Vault?

Answer:

This is working as designed, as the CRM Territory field is required to be on Approved Email Document Types for the Vault to CRM Approved Email integration. As such, the ability to remove this as a Shared Field on Document Types is not available in order to prevent from erroneously breaking this integration.
