Theme applying to aliases and other members but not my main account

Most of the edits I'm making to my site's CSS are only showing up for other accounts. When I view the site from my main, all that's changed are the fonts and the new custom membergroup colours. It also seems that changes to HTML are saving fine, since I edited my main profile code a lot and that's all showing up. I've checked in the ACP that there's only one theme, and I currently don't have the light/dark toggle enabled on my site. The pop-out theme editor, and the ACP stylesheet, both show the edits that I've made, they're just not conveying to the site for some reason.
