Thanks for the template file, I was able to reproduce this issue just as you have stated. I did some investigating and I have found the problem, it is the way that you have your editable region for the head setup, currently you have it like this:
<!-- TemplateBeginEditable name="head" -->
<head>
</head><!-- TemplateEndEditable -->
If you update it so that the head tags are outside of the editable region then this will not happen, like this:
<head>
<!-- TemplateBeginEditable name="head" -->
<!-- TemplateEndEditable -->
</head>
When I create a template from within DW it seems to default to having the head tag outside of this editable region. So long as you have the head tags outside the region it should work as expected for you. Let me know if you have any other problems with this.
