@hsandstrom: Hello there,
You seem to have used the following Code due to which the overlay is showing up.
#hero-section.has-section-background-image:before { background-color: rgba(0, 0, 0, 0.8); }
I will need to look into your site to remove the CSS Code. I have sent you an email. Please check your inbox as well as the spam folder.
Kind Regards,
Skandha
