Hello, @antonia,
I can see you have set the width as 1000px, and that is also too much for the laptop screen sizes, actually, for perfection, you have to set the width as 738px so that the complete dropdown menu box will appear under the complete menu width like this: https://postimg.cc/w3cp4Rw6
So try to change the width as 738px and check back your site after clearing the browser cache.
Otherwise please share your site WP Admin URL and Credentials with me in a private content area of this topic and also please let me know your laptop screen size as well on which you are facing this issue, so that I’ll check and help you out further.
Regards 8Themes Team.
