White Box Found In Footer Above Social Buttons

What an amazing theme you have created. I truly love it. I am however just discovering an issue I just noticed. In the footer where the social media icons are located a rectangular white box has suddenly shown up. It does not seem to link anywhere. It disappears if I no longer have the social media icons active. Any idea what this could be. I have the latest version of Wordpress 4.9.4–en and the latest theme updated Version: 1.5.1. Any help would be appreciated. Thank you. http://www.theminstrel.net
