Hello Allan,
As per our analysis there are two things due to which this might be happening:
1. The Showcase Area of your website does not have any minimum height, due to which the elements where Animate It! classes are applied comes to the visible area of the window. This makes them Animate immediately. Please use the below code to set minimum height for the showcase area:
.so-widget-sow-hero{
min-height: 500px !important;
}
2. The Scroll offset is set to 75% under "Settings -> Animate It" due to which, on large screen sizes, the elements are almost in the visible area of window so animation occurs immediately. Try to adjust the value greater then 75% like 100% or more than that to achieve on scroll animation.
Let us know if it helps.
