Home Page Modules Not Full Width

Hello – I am adding text modules on the home page and adding color to the backgrounds to break up the sections. I have the theme set to full width, however, the modules are acting more like they’re a fixed-width and have space around the edges (see images). How can I ensure they go all the way to the edge of the window (responsive)? Please note: I am not talking about the slider image/header here. Thank you!
