Hi,
I see it already appears on your header - check this image: http://prntscr.com/10ym1wm from the plugin "All in One SEO Pro"
So, I think it will be fine now and you can remove the code you've added via Customize > Logo and Header > General > Add Custom Code Inside <head> Tag. Because it will appear 2 times.
Best Regards,
