I have created a document and have activated display chord diagrams at the top of the flow (hidden on the staves themselves). I have edited various elements of the third diagram in Engraving Options. However, I wish to change the font of the guitar fingerings inside the filled black circles. I have navigated to Library > Font Styles > Chord Diagram Fingering Font and made changes to the font font style and size, pressed okay and nothing happens. I have saved the document and reopened and it’s still the same. It can’t be that complicated surely? Any ideas? File attached.
