Delete and Delete All options are not available to administator

I been trying to delete all Incidents from a now longer needed Process version. Unfortunatly the "Delete" and "Delete All" options are not available for the SA user(or any other) in the Console.

Can this be configure as a  separate permission or process step? Is there a way of enabling this to all admin users?

I would like to avoid any need of running scripts directly in the database.
