Wix Expert

Hello, I have this page https://www.alexis-webdesigner.com/copie-de-home and I used a scrolling code on Wix Velo On Google chrome, it's not working perfectly as you can see on my link above. The code I am using is this one: https://www.wix.com/velo/example/full-screen-scroll Could you help me improve the code to fix the issue to have a clean scroll? the issue especially happens when scrolling up from the last section, looks like it goes to the first slide/section quickly then go to the second slide/section instead of directly going to the second slide (you can see a flash or sometimes it directly brings back to the top of the page) Can somebody help me?
