Clumped up elements & sections

The elements on my websites are all clumped up together when I initially open my Webflow website but when I scroll down the elements suddenly position themselves where they are correctly meant to go.

What’s the best way to fix this problem, please?

Here is a read-only link to my website:

P.S - The website is not finished so if you see some unfinished bits now you know why
