Hello Bob,

To modify a Template that is included in the Program you select it and then you click on duplicate. It will be created a copy which can be edited with a doubleclick in the copy. It will appear the template editor where you can change all the settings of the template.

If it's a custom template you can edit it with a doubleclick or if you want to change only the graphic of the header/footer you can do it in step 1 - Edit Graphic Template.

Please feel free to write back if you need more information.
