Dreamweaver intermittently adds extra InstanceEndEditable tags

Question

Twice in the past couple weeks, members of the team I work with have updated templates, then tried to update a page associated with the template.  The update was not successful because Dreamweaver had added extra InstanceEndEditable tags to the page. 
Here's what we should have seen:
<div><!-- InstanceBeginEditable name="example" --><a id="123" href="http://www.example.com">Test Example</a><!-- InstanceEndEditable --></div>
Here's what we saw:
<div><!-- InstanceBeginEditable name="example" --><a id="123" href="http://www.example.com">Test Example</a><!-- InstanceEndEditable --><!-- InstanceEndEditable --><!-- InstanceEndEditable --></div>
Another team member would then get the updated template and apply it to the same page, but this time, Dreamweaver would not add the extra tags.
We haven't figured out a pattern here.  The templates and pages are otherwise correctly coded, and they don't have other issues.  Has anyone else seen this problem?  If so, is there a way to prevent it from happening?  Thank you.

Unless the issue is 'reproducible at all times', it cannot be treated as a bug. In your case, since it is intermittent, I think it's more of a behavioral pattern - so from now, for a few days, can you make a note of your workflow at all times and notice when or at what stage this happens? This will help us identify its cause.
