I adopted a page recently and keep trying to fix the background image and color for both light and dark modes, but they never show up. They only seem to appear on the discussion page, but everywhere else, it's just a white background for both and no image for either one. Is there anything I need to do to fix this? I run another page, where I am able to edit the background without any problem, and the Theme Designer settings here look about the same. I linked to the main page and the discussion page so you can see what I mean.
