Font size not showing under blue box

When I go to the basic settings/body content of the plugin in my theme genesis/parallax pro..I chose Open Sans as the font, then clicked on the blue box..but all that shows is style and weight but not size, color or height. I want to change the default size to 19.2. I even went into the theme editor and changed the font size to match 19.2..but when you inspect the page…the body size etc is lined out showing it is not responding to the plugin settings.
Is there something I have not set correctly that is preventing the size from showing under basic settings for body content?
