Accidentally deleted “Add On” menu item from main menu

Hello,

I accidentally deleted the “Add On” menu item on the main screen (Movies, TV Shows, Music, Music Videos, Pictures, Videos and Weather). How do I add that menu item back onto the menu?

I thought I’d be OK by uninstalling Kodi 17, but even when I reinstalled, it still leaves the Add On menu item as deleted…

I would appreciate any assistance.

Thanks,
Rick R.
