Orange-highlighted inherited selectors in Style Editor

Thanks. Sorry, if I go to body (all pages), is that in the Style Manager tab? I selected that and saw all the pages which were affected, but what does that tell me?
I have ended up adding an Adobe API token on the font settings page, specifying the fonts and re-editing webflow to select these fonts. The thing is, none of that was there before and was not needed - the Adobe section in the Fonts tab was empty and the website was fine for months until 2 weeks ago. Do you know why this would have suddenly happened and if what I’ve done is what I should have done, or have I created another problem down the line for myself? Thanks for your help.
