Word - Stop MS changing stylesheet font

I have several stylesheets that use the the Callibri font for headings.
When I create or edit and print or save documents, they appear as I want
them to. However, when I open the document again later, MS has changed
the headings to Cambria font.  Nothing I do seems to prevent MS from
making this undesirable change.

Can anyone tell me how to fix this?  I am using MS Word 2010.

In the Templates and Add-Ins dialog box, make sure that "Automatically open
document styles" is cleared. Then you can modify the styles as desired.

To display the dialog box, click the Document Template on the Developer tab. (If
the Developer tab is not showing, click to display it in the Customize Ribbon
category of File | Options.)
