Plugin Calculated Fields Form conflicting with Customizr theme

The Calculated Fields Form plugin is conflicting with my Customizr theme. I have disabled all plugins and switched to the 2015 theme to verify where the problem lies, and it is the Customizr theme and this plugin that is creating the issue. What it is doing is displaying my header oddly. Here is the link to the page where my issue is. Is there some CSS or something that I could use to fix this?
