Background Images suddenly disapper

Hello - I’m using BB lite on my client’s WP website and the background images are loading fine in the backend and even when I first publish it. But once I refresh the page, many of the images disappear and even some of the columns stack even though they weren’t designed to. I do NOT have breakpoint set to anything specific and all should be visible.
