Mobile Menu does not show all the links on dropdown on some of the pages


On all pages except the homepage, the dropdown menu in mobile version does not show all links.
In the Designer, everything is ok, all the links from the drop-down menu are shown, but when I preview the site, it looks like the navigation menu is cut. Strangely, when I resize the page of the browser, the links appear.

Would really appreciate your help!
