Make sure that "Automatically update document styles" is cleared in the Templates and Add-Ins dialog box. Then you can modify the style so that the changes stick.
To display the dialog box, first display the Developer tab and then click the Document Template button. Here's how to display the Developer tab: Click File tab | Options. In the Customize Ribbon category, click to select the tab.
