Thanks for updating in!
The theme option settings for the typography is working as expected. It does not apply to your page which you have created with the Pro builder because you have set the font to default. You will have to keep in mind that both the text element and the headline element has its own default settings. It includes the font, color, size etc.
The theme option typography settings will only be applied to the elements on the page if you are not using Pro editor and have used the default Gutenberg editor or the classic WP editor.
Hope this helps.
