Brave show all pages in ONLY light mode or ONLY dark mode

I have a similar problem as here I cannot disable dark mode? - #8

My problem was that out of nowhere, all pages started to appear in light mode, even though I have dark mode on them in the settings after logging in (google, linkedin, etc.), for example, facebook was still displayed as dark mode (wtf?). - in private window problem persist

I used the advice from the linked question, but now I have everything in dark mode, the entire internet content. How to go back to displaying only pages in dark mode where I have it set after logging into a specific account?
