Targtag Attribute Not Working

I have tried to use the targtag shortcode attribute, but it doesn’t appear to be passing the tag when the content is viewed. I looked at your example, and it is supposed to pass the “strong” tag to your content, but it is not doing it there either. I looked at the source and don’t see it there. I am a pro user, and it would also appear that it is not assigning when I try to put it in the Plugin Settings as well. Thanks for your help.

Taken from the source of your example:

<a name="targtag"> </a></p>
<h2>Targtag Attribute</h2>
<p>The targtag attribute replaces the default html tag that wraps the target content. By default the html tag is <em>div</em>.<br />
<code>[expand title="A Long Time Ago" <font class="highlight">targtag="strong"</font>]Target Content[/expand]</code></p>
<div class="example"><span class="collapseomatic " id="id8561"  title="A Long Time Ago" >A Long Time Ago</span>
<div id="target-id8561" class="collapseomatic_content ">…in a galaxy far, far away.</div>
</div>
