SwiftUI NavigationView background

Hello everyone. Can someone please help me. I am completely lost and have exhausted everything I know to do. I have a Navigation View with a list inside of it. For some reason, there is a gray background behind my list. I'm assuming this is due to some type of padding with the Navigation View but I can't seem to be able to adjust the background or change it to clear. I have attached an image of what I'm mentioning to hopefully better explain. You will see the green bar at the top. that is the background of another view behind this view. I want to either fully cover the screen with the gray background or remove it completely.

Code? Let us see your code so we can figure out what is causing it, and provide you a fix.
