Issue
ITIL users are not able to view any change fields that will be auto-populated using macro in "Propose a new standard change" template catalog item.
Cause
This can be an issue with ACL.
Resolution
You will have to create an ACL with an operation of "save_as_template" for the Change Request table (change_request.*).
You should also add the itil role (or whatever role you desire to require) to discriminate further on the ACL.
