Cliona O. so I'm not 100% sure if I'm understanding you correctly or not, so if it seems like I'm not please let me know!
But basically it looks like the last item isn't sticking to the bottom of #3 like it originally should have. The values for your top position seemed to be quite a bit off from the original component.
Your navbar is sticky, and I'm assuming we want to compensate for that - the navbar is about 5rem. So if we start the first item off at 5rem, second item at 10rem, third item at 15rem, and the last item at 20rem, everything should scroll up how I would expect it.
The anchors should be set to -12rem. But you might want to bring that number up or down depending on where the scroll lands after clicking.
To make it easy on you, I've created a new Webflow project with vanilla components in it so you can inspect closely how the unedited version of this component looked.
