@TG2 thank you so much for the tip! I could not understand why my custom Open Sans woff2 files are not replaced by WF and I still have 12 styles that I do not need.
My blog runs much faster now thanks to you. It’s such a simple fix yet it has not been addressed yet by the WF team.
Thank you so much for this!! You just saved me a LOT of time. But more importantly, a lot of site load time haha 
ha :
I don’t have this problem as I load 1 font and yes it took a long time to clean it up.
But your tip here is spot on and learned a lot, so thanks for posting this.
