I am trying to add update "Resolved" status as a post function in my workflow, for tickets that have been closed. However when I go to the "Add Post Function" page, select update issue field and select "Resolution", I am unable to select "Resolved" or "Unresolved", as they do not appear in the drop-down list. There do appear to be several custom entries, but I know that the resolved and unresolved status are used on other projects.
Is this intended functionality? Or is it likely some settings have been altered on this field by an admin or something?
