Sections visible scrolling down, disappear when scrolling up

Hello,

This is my first time building a webflow site.
It’s a simple one pager, with accordions that open and close (only the first one #20 is working for now).

While I preview the site, I can scroll down and see everything, but when I scroll up, it all disappears and i have no way to get back to any point on the page. Could this be due to overflow settings?

Also, I’ve followed the set-up of accordions (hide/show), but sometimes it appears as if there’s a giant gap (as if the accordion content is still there taking up space but not visible…?)

Please help! On a deadline and this is something I cannot seem to resolve!
