Homepage scroll issue on mobile

Hello! I have used the free version of Catch Fullscreen to build a website (https://www.rickykoole.nl), which seems to be working fine on desktop. However, on my phone, the header is not responsive to swiping to scroll to the next section. I am able to navigate through sections using the side navigation, but I can't seem to get the gesture to work. On a desktop computer with a trackpad, I have no issue at all. Is there a way to fix this with custom css? Or am I missing a setting in the customizer? There is no option to use normal scrolling in the theme settings — but if that is the easiest fix, I'll take it. Please advise. Charlotte
