Overflow hidden glitch

Hello, there’s this glitch on this site that im working on. I had a unwanted horizontal scroll on mobile. When I set overflow on my sections to hidden it solved the issue. Whenever I change the overflow to hidden for the hero section it makes an element not visible on mobile. What’s the issue here?

In designer everything is visible

on phone the illustration has disappeared

Alright, i deleted the element and uploaded it again and that seemed to do the trick
