looks very like a Table of Contents without page numbers :-} try this …

1. type Alt+I, then F to open the Insert fields dialogue
2. scroll down to TOC and click once to select it
3. click [Table of Contents…]
4. clear (deselect) the Show page numbers checkbox
5. click [OK] to generate a new Table of Contents without page numbers

note: I don't have 2007, but suspect/hope fields haven't changed much
