Custom CSS theme keeps being reapplied on android launch despite no CSS support

When I open Fluxer on my android phone, on the latest version, it will change the theme to a CSS theme that i often use on my laptop. This issue started today, after I got a system message that was telling me to update, so I did, and now the theme keeps becoming the CSS one whenever I open Fluxer on my phone, which is impossible to change on android as far as I'm aware, and only happens with the specific theme, but not any other themes.

I have no Idea what has gone wrong, it was just like that when I opened the Android app, even before I updated the app. I do not have the CSS device sync enabled.
