Ok, I think I know... content below, after scroll down. You made mistake, in that Row/Section you used negative margins, here is CSS code that was used:
.sp-page-builder .page-content #section-id-Q6c6mJ5zr3wjEF17lrbBY {
margin-top: -120px;
margin-right: -120px;
margin-bottom: -120px;
margin-left: -120px;
}
if you really need it on desktop view (???), change value for Mobile view (!) here

For Mobile view use normal values, it can be 0px or 10px. But never negative (-) , remember that simple rule. Don't make simple things harder. Have a nice day.
