Not sure what that 'Home' references to but it's not necessarily an app. An installed app typically get its icon added to the app menu, but items incorporated into the Settings menu get put there by the manufacturer or the carrier, changes to the Settings menu are done at the system-level. You can change options in the Settings menu but don't have that kind of ability to actually change the Settings menu. And the Settings menu is a direct reflection to your specific phone model. Every phone model has its own unique hardware configuration so the Settings menu in one phone won't be the same as in another phone because not every phone has the exact same capabilities or functionality -- i.e. if you phone doesn't support NFC, there isn't going to be NFC options in the Settings menu, or if ZTE includes some kind of feature in its phones there's a difference between ZTE specific features (just in ZTE Settings) and common default Android features (in all Settings menus).
Are you sure that Home was just recently added to your Settings menu and it hasn't been there already?
What happens when you tap on it?
