Spontaneous header padding increase

The header styling for padding on https://www.shapeddecks.com/ has been set to two on the slider both above and below the header since day one. With those settings, there was the same amount of space above and below the logo. As you see now, the padding below just grew quite a bit out of nowhere (I checked the padding settings, still the same, and even if I set it to have no padding below, there still remains a huge blank space below, very little change to what you see now.) Any ideas why that may be or how I can fix that? Thanks!
