Mobile theme not working correctly – Homepage / Scrolling content

Hello Catch Themes staff, I used your Catch Fullscreen Theme for about a year by now. Afte the last update the theme seems to have a display issue. A quick description of the website: A custom header image is added to the website, a scrolling content wheel on a second section is added. The third section is a widget part. The problem is that the custom header image is too small. So the next section is bleeding through to the first section. The same problem is occuring with the third section. Some Custom CSS is used on the website for custom designs but the problem presists after removing that. Some help and ideas are very much appreciated. Heres a screenshot of the problem: https://blumen-natur.de/wp-content/uploads/2020/11/Catch-Fullscreen-problem.jpeg
