Hi Nathan,
Is it the “Inspiration You Can Hear” text you are referring to? If so, I have checked and this text is generated by a plugin you are using and the plugin is overriding the font you set in the Theme Options.
Perhaps there is a setting in the plugin where you can set the font of the text. Please also note that since this is a third party plugin, we cannot provide support for its setup.
You might have misunderstood how the Font Manager works. The fonts you have added in the Font Manager will not take any effect yet. You are just merely adding fonts there that you can use on your site.
By default, there Font Manager have the Body Copy and Headings fonts. You are free to delete these since these are just fonts you want to use on your website.
You can just have one font if you like.
Then you can go to your Theme Options and the Pro builder, you can find the fonts you have added in the Font Manager in the font settings. For example, when you go to Theme Options > Typography > Body Font.
If you select the option, you can find the 4 fonts you have added in the Font Manager as the options:
There is the Headings Font setting in the Typography option of the Theme Options.
Headings Font will actually affect headings such as h1, h2, and so on.
This might just be a matter of knowing how the Font setup using the Font Manager work so kindly take time to read our documentation for the Font Manager which explains how it works in detail:
Hope these explains it.
