No, you shouldn't have to do this all the time. The setting is document-specific.

Since it happens with all documents, your Normal template has tracking enabled. Open the template as a document, accept changes and turn off the tracking. Save and close the template.

To open Normal as a template, you can do the following: From within Word, press Alt+F11 to display the Visual Basic Editor. Press Ctrl+G to activate the Immediate window. Type

NormalTemplate.OpenAsDocument

and press Enter. The template opens in a separate window, which you can tell by looking at the filename on the title bar. Close the Visual Basic Editor. Modify, save and close Normal as mentioned above.
