How to fix the pages transition

Hi, I made a portfoilo website and I try to make that if people want to see the project, click it and go to another page.

The problem is if I keep scolling from the home page, the page chang in to next project page.
I don’t want to switch the page by scrolling but I can not find what is the problem.
The problem did not appear at the edit version but only in published one.

I hope, I could find the reason.
Thank you.
