Since I have the link to your site already, I just checked and it appears you have an extra <p></p> tag/tags appearing in your code. This can happen if you manually added it inside the widget area itself. It can also happen if you checked the box on your text widgets labeled – Automatically add paragraphs (on your widgets page). It will add a paragraph tag anytime you press enter or add a new line. So check to make sure your text/code starts at the very top with no space in between.
