So I'm trying to burn this DVD using Movie Studio 2022 Platinum. I guess this is the main menu page for the DVD. https://gyazo.com/ad5217eb51650dddfc3bae536756990e

What I'm trying to figure is out what do I do with the red outlined box on the left and the one next to it. I get that the red outlined box takes me to the chapter page, but am I supposed to be able to change the image on it? If so, I can't figure it out. and I get that the box next to it will just play the video. But again, am I supposed to be able to edit that box, and if so how?
