ShrePoint Online Modern Site Does not display global navigation


I have a SharePoint online site with 5-6 Sub sites within it.All are modern sites.I have set the Global navigation setting to “Structural Navigation: Display the navigation items below the current site” with “Show Subsites” option is checked. That’s it. I don’t see the subsites over the global navigation over the site home page. when I go to site settings.aspx page there I can see the navigation does displays thse subsites over the Global Navigation section.

Kindly help in resolving the issue.
