You said "...go to: Build, Templates, Event, (find) death certificate..."
OK, we're getting warm.As Myrnice says, that's not a normal UFT event template.Please tell us what it says in the GEDCOM field and what it displays when you click on the "Source" button.
It appears that either you created this event template or you imported a GEDCOM from someone which included this template.Or maybe it's something left over from some ill-advised templates issued with ROOTS IV.
In any case, you can change what it prints by clicking on the role "edit" button, selecting the role involved and modifying the role sentence.
BUT if you have not used this a lot, think about what the death certificate itself really is - it's not an event as much as it is a source of information - and there's already a source template for it in the standard UFT set.You may wish to avoid the use of this event type.
