Lottie export showing items outside the composition

I am newer to working with lottie. I created an animation where documents come on the screen from outside the composition at the bottom. When I create the lottie file, it shows items below the bottom line when I don’t want it to export anything other than what is in the composition in after effects. (The top image shows the animation in after effects and the bottom is a preview of the lottie json file).
