I've tested this in IE and Firefox, it breaks it slightly differently in each but neither will toggle the first section. All other ones work.
You can see here http://columbusohiowebdesigns.com/?page_id=50 has the demo content, to verify the bug all I did was add the shortcode for the drop cap before the toggler and save the page. You can click on the first toggle but it will not display the data.
