Note: -- The Item ID which has been entered is from the parent menu item which can be seen in screenshot
-- In similar way, If you wish to have different title and description for respective page, You can try create "hidden" menu item by toggling Display in Menu to No in link type sub-tab for specific menu item and assign menu item type - single article
-- Add specific article to particular menu item
