Scroll into / out of view animation - a WF cloneable site


I cloned a featured Made in Webflow site, but I don’t understand how the backend matches the front.

Settings on the backend:
When scrolled into view: Fade out
When scrolled out of view: Slide in

Actual behaviour:
When scrolled into view: it slides in*
When scrolled out of view: it slides in*

*can’t tell but I think it does a bit of fade as well

The animation itself is lovely, I just can’t understand why it’s behaving unexpectedly.

Here is my public share link:
