Replaced cracked screen and top of screen is not responsive.

I replaced my Google Pixel 4 screen last night, everything works on the screen as it should except the top portion of the screen will not respond to touch or tapping. It won't let me swipe down or tap on icons in the top left or right corners to open them, for example I can't hit the back arrow on a screen but I can swipe to the right to return to the previous page. is this possibly just a bad connection on the screen? Or a faulty screen?
