Inconsistent Google Font Loading

If anyone could help with the issue I’m facing I’d really appreciate it.

When Autoptimize is enabled, my google fonts are not consistently loaded on all pages of my site. In the page I linked, instead of Libre Baskervill and Lato, just default Arial is loaded.

If I had to guess, the fix is excluding something from being optimized, but I’m not sure what.
