Issues with the WarCard Game

I am currently following the iOS Tutorial (2020) video on YouTube and am creating the WarCard game. I am having issues with the background fitting with screen orientation and I’m not sure why as I have followed all the steps in the video. Does anyone have any ideas to fix the problems I am having?
I have included an image to show the problem I am having.
