Missing "Project Reports" header in the generated menu

The generated site is missing "Project Reports" header in the generated menu. The resulting source looks like this:

<div id="menuProject Documentation">
<h5></h5>
<ul>
<li class="none"><a href="index.html">About</a></li>
<li class="expanded"><a href="project-info.html">Project Info</a>
<ul>
<li class="none"><a href="mail-lists.html">Mailing Lists</a></li>
<li class="none"><a href="team-list.html">Project Team</a></li>
<li class="none"><a href="dependencies.html">Dependencies</a></li>
<li class="none"><a href="cvs-usage.html">Source Repository</a></li>
<li class="none"><strong><a href="issue-tracking.html">Issue Tracking</a></strong></li>
</ul>
</li>
<li class="collapsed"><a href="maven-reports.html">Project Reports</a></li>
<li class="none"><a href="development-process.html">Development Process</a></li>
</ul>
</div>

As you can see, the <h5> tag where the heading should have been, is empty.
