Top two images are not displaying on mobile

When I view my site on mobile, the first two tile images don't display. They collapse into a vertical view, but the top two just show up as a white space. Blank white spaces. Sometimes when I refresh the page, they will appear, but it is infrequent. The same thing happens when I view my shop page on mobile. The first two products do not display. https://mattserafini.com/ https://mattserafini.com/shop/
