Custom code appearing above my menu and header

I changed something on my website, but now this custom code is appearing above my header and the menu looks out of balance. I checked the header injection code and couldn't find anything wrong there. What could be the problem? 

The website is www.peterorsel.com.

You can check on home page setting:

Ah yeah that helps... Feel so dumb when the solutions are that easy. Looking for all custom codes but couldn't find anything, but there's a custom code at the home page as well...
