XD marks fonts as missing, but they are not

Adobe XD displays fonts as missing with orange exclamation marks. I still can use those fonts, but those exclamation marks are very annoying.   

Would anyone happen to know how to fix it?

Thanks.

@Zaber348089477hku I would select one of the fonts and re-direct to that font family, and all of the exclamation marks should go away. When I open students homework assignments, I just have to re-direct it or reload the fonts.
