Plugin adding a margin only on homepage

Hi! I am using the plugin to display a CTA bellow my header. Now, it goes across all pages and works well everywhere except on homepage, where it adds a margin and the website brakes out the browser window. For the life of me I can not figure out why is this happening! I hope you will find the time to have a look and let me know what is causing this problem. The website in question is atilairmes.com

Best regards,
Atila
