This causes a "style not found" message, because Word tries to find "Heading 1" when that style is now called "Titre 1", for example. to the local language when you switch Word language versions.

Word translates the style names of the built-in Heading 1, Heading 2, etc. NOTE2: If you use different language versions of Word at the same time (the UI language, not the document language), edit the field codes and replace STYLEREF "Heading 1" with STYLEREF 1. One pointing at the number, and the other one pointing at the name. NOTE 1: If you want the chapter number AND chapter name in the same header/footer, insert this field twice.

To insert the chapter number instead, select the Insert paragraph number check box.

Select the Preserve formatting during updates checkbox.In the Style name list, click on Heading 1.
