Some shortcodes has another background

Hello so basically I’ve first made my website light theme (white background dark text) then switched to black theme (grey/black bg white text) but for some reason some shortcodes appears with white backgrounds and I can’t seem to find a fix (i tried changing all plugin CSS that had white background to black but doesn’t change anything).

Here are some images
