How To Reset Typography (To Fix WPML Font Issue)

I have added some google fonts at Appearance > Customize > Typography. And then I figured I need to customize different fonts for different languages. WPML told me to fix this at CSS but customized CSS can't override inline fonts entered at Typography. So I figured I need to delete anything entered at Typography so it can go back to the default theme font and there won't be inline styling. I'm not able to do so because anything I entered previously e.g. "Roboto" stays in there even after I deleted Roboto in Font Manager, and even the selector in Typography is showing blank. In front end the font is STILL "Roboto" as defined inline. How do I reset the Typography to "factory default"?? Or is there another way to fix this? thanks.
