The ability to edit templates depends on your permissions.
We have two ways of editing a Template.
Editing a Template from the Create / Edit Issue dialog - allows you to edit a Template in a quick way, from Create Issue Dialog, Create Sub-task Dialog and Edit Issue Dialog. Use this approach, if you want to edit a Template that created for the sub-task.
Editing a Template from the Manage Templates page - allows you to edit a Template, from Manage Template page, that helps you view and change all the available Templates in a quick way.
