Mythical white space on top of product page

So I read a lot about this, I found other people had problems like that, and tried a lot of css, but none seems working.
My problem is, when you go to any product site, the single product site, there is a big white space above my page, myheader part, and I can’t get rid of it.
I think that os the .site-eader div from the basics wp theme, but even when I put a display none and overflow hidden on it, it’s still there.

The strange thing is, when I make a new single product page with the elementor theme builder, it’s always there, but seems to appear only at the single product page.

The page I need help with: [log in to see the link]
