Are you sure that the built-in headings are not called Overskrift 1, Overskrift 2, etc.? Those would correspond to Rubrik 1, Rubrik 2, etc. in Swedish and to Heading 1, Heading 2, etc. in English. (Title and Subtitle are separate styles, not part of the standard headings.)

To see all styles, look in the Styles pane (Ctrl+Shift+Alt+S). Click the Options link at the bottom right which opens a dialog box that let you choose to display all styles.
