Issue with Products Archive

I am using the "Hello Theme" because the default Wordpress theme was causing major issues with formatting for my products. Your theme seemed to fix my main issues. But when I try to edit my products archive, I make changes in the Elementor editor -- visibly able to do so -- and they don't seem to apply to the live site (once published). I'm attaching two photos to show what I'm talking about. I'm not sure why things look fine in the editor, but they don't look fine in the live site. I want things to be centered, I want the price to look a certain way, and I want my "Add to Cart" button to be brown. I'm posting this here because I'm assuming that this might be an error (as I'm using an Elementor theme with the Elementor editor).
