Parallax scrolling issues

Hey everyone,

I’m making an attempt to create a parallax scroll in one of my sections. Im finding that my results are quite different when i publish it vs scrolling live while in webflow. Aside from that im also finding issues when the height of the browser is altered. I thought i might fix this by using VH instead of pixels but i think it might be worse off that way. If anone can let me know what I’m doing wrong or if i missed a step please let me know.

Check the parallax in the ama/aha section (its the purple one)

Here is my site Read-Only:
