Dear Stefano, Could you please tell what document class you are using. In "book" this is exactly the case: Chapter 1.
(Document settings can be seen by view->source->complete source; there is something like \documentclass[oneside,english]{book} where "book" is the style.) I assume that your class is different, but perhaps the easiest way is to change the document class itself through "Document settings" menu.
