1) Theme Options > Typography. It controls the Body font and Headings font family. All the elements on the site inherit these fonts if other is not changed in the personal element settings.
2) Theme Options > Header builder. And there are a few places to change the font of the header or menu elements if you need that or keep default settings and then the body font will be used.
So please try to check it again with these settings and also try to clear the cache and check back and if the issue will still persist then please share the screenshot of the section so that I’ll check and help you out accordingly.
