Changing fonts

Hi,

Sorry if this might sound trivial, but I’m having a hard time changing the fonts with Engrave. It’s advertised that you have over 600 google fonts to choose from. I’ve installed the google easy fonts plugin. But my applied changes in the “customize” section are not taking effect on most of the content on the site that I’ve inserted using Page Builder and widgets.
My site: https://www.julianpowellphoto.com

Would appreciate any suggestions (I’m sure there’s a really obvious solution that I’m missing).

Thanks,
Julian
