Did you recently get a new screen?

If you are getting notifications about a screen being ungenuine, then I appears you've placed an ungenuine screen in there. So, return this screen, requesting a genuine one.. The seller should have known better. Elsewise, you'll continue getting the notification.  Learn More here: About Genuine iPhone Displays - Apple Support
