Position Sticky Side Bar Is Not Working!

Hi everyone,

I’m trying to apply position sticky to the right column of the element that succeeds the hero section on my site but the effect only triggers for one scroll. I’ve watched the tutorials and have done my best to apply the best practices but it just wont seem to work. Would anyone please let me know what I’m doing wrong?


Here is my site Read-Only: [LINK][1]

It’s the Split section on the right hand side that I want to apply sticky positioning to if that helps. Any ideas what might be wrong?
