Extra <div> under headings in chunked

[David Pratt <prattda@assiniboine.net>]

I am chunking xhtml output using 1.60.1 and now 1.61.0 and get an extra set of <div> just following each heading.

This occurs in both xhtml or html versions using the chunk.xsl

I have been through the sections.xsl where this all seems to be occuring but can't identify the source of the extra element to correct this in a customization.

Assistance appreciated.

The output looks like this:

              <div class="titlepage">
<div>
<div>
<h3 class="title"><a id="id520476"></a>2.1.1. Overview of Chapter 2</h3>
</div>
</div>

</div>  <-- this is the element set I want to remove
</div>
