Seems like there could a very simple solution but I'm really at a loss. Under /admin/appearance/font the Browse section displays empty results for any criteria I input.
Installed latest version of module, enabled it, drush cr'd and headed to /admin/appearance/font and attempted to Import fonts under settings and then Browse to add them.

@bindslind, have you selected a fontyourface contrib module like google fonts or adobe fonts? You need to import fonts in order for them to show up in the view. If its not already, a fix might be to show text if the user imported fonts.
