Running Header not using last header on next page



I have a running header set to to display the first ( or last--I've tried both) instance of my title paragraph style that occurs on the page. This works fine with page 4 containing my introduction and page 5 containing a list of materials. However, my materials list runs on to page 6 and I would like for the running header to reflect that reality. Instead, the running header for page 6 displays my title from page 4. How to I get it to display the title from the previous page when no title is specified on the given page?
