Issue with Image Loading in Section Layout 348 on Webflow Project

Hi everyone, I got an issue with section_layout348. You can see how it works here - projects section: https://symbolon-2.webflow.io Initially, the images took a while to load. I compressed them, and they seem to work okay. However, when scrolling down to the next sections and then back up, the images do not load at all. Any idea what’s wrong? Thank you in advance!
