Deleted menu stays visible

I deleted the menu in appearance>menu, because i only want to have a “home” and “about” in the menu.

Somehow the menu still is vissible in the main page. What do I need to do to remove this?

Hello there,

Please visit the custom menu administration panel (Appearance > Menus >) once again, and then make sure you are editing your active menu identified by active Primary Menu in the Menu Settings section above the Save Menu button. Then delete the unnecessary menu items.

If the changes are unnoticeable, there might be any other circumstance which blocks this. Please checkout this codex which will help you resolving it.
