Extra P and SPAN tags

Hello! Love the plugin.

I have a very simple snippet of HTML for a call to action that I drop on the bottom of each page. However, when the code is outputted, it includes a <p><span></span></p> above my HTML. There is nothing in the HTML tab above my code. What’s going on? How do I get rid of this?

Thanks!!
