some images are not fully displayed

Hi, I looked in your demo and scroll down all the pages, all is fine. When I scrolled up, I noticed, that in some cases a part of the previous image remaining on the bottom. Let me give you some hints: 0. open your demo at https://catchthemes.com/demo/catch-fullscreen-pro 1. scroll down to section #latest-post-5704 2. scroll one section up to #latest-post-5296 and take a look at the bottom 3. scroll down to section #latest-post-5700 4. scroll one section up to #latest-post-5704, same problem here 5. scroll up to section #latest-post-5296 6. scroll one section up to #team-section, all are fine here greetings
