The problem is that you are linking the page to the id #intresseanmalan, so the page jumps right into the there when you access your link.
If you want the content to stay visible after jump into an id, give it a padding-top a least the hight of you navbar, you can give it a negative margin-topwith the same amount, so if stays on the same position.
The scroll effect is already built in on Webflow, you just need to make a internal link to an id, but it needs to be on the same page.
