New to Webflow and confused about how cloning websites for animations works

I’m using this link as a reference for a project I’m working on. I want to use the first effect on the page for the text on the website I’m creating. I cloned this page and copy-pasted the section and changed what I wanted to, but the animation doesn’t work.

I took a look at the interactions panel on both the cloned website and my copy-pasted section and they seem to be the same

To give more context, if I clone the website and make any changes on it, it works, but copying sections into my custom website causes all animations to drop

Coud anyone help out with this please? I feel like it’s an issues that’s very obvious, but I’m missing something staring me in my face. Thank you!
