I had this issue since gnome-control-center 43 came out in the development release of Ubuntu 22.10. I found another post for the same bug and made it a duplicate so it's linked here.

When setting the style through the quick menu however, these apps go to Dark mode (presumably due to gtk theme being applied). Likewise for the quick menu itself, setting the style to Dark in gnome-control-settings doesn't change it to dark, it remains light. see screenshot attached, you will see that when setting the style to Dark in Settings, gedit and the quick menu remain light. I tried to logout in case it was an issue with how the settings are applied but it didn't help. it's also clear that the toggle in the quick menu works as intended so there seems to be an issue with the way gnome- control-center applies the Dark style.
