My earlier question remains: what is it you want to fix?

Look at the Add-In I gave you! Try it out. It gives you two options using a single template or using two.

Put the one in the package that has "Add-In" as part of the name in your startup folder if you want and change it to what you want. Otherwise, you need to set up your template to work the way the Add-In works.
It is fairly well documented. Click on the question mark in the QAT.

The one labeled StartLetter.dotm is an alternative that requires a separate template called Letterhead.dotm in the Letters & Faxes folder of your Workgroup Templates folder. The StartLetter.dotm file is its own documentation.
