FOntSelf 3.4.5, OSX Catalina 10.15.7, AI 25.0.1. When I try to delete a character that has alternates, naturally Fontself tells me to delete the alternate first and then delete the origin. After I delete the alternate, I no longer can delete the origin - clicking the trash icon does nothing. So I save the font, quit Illustrator and when I start it again - I now can delete it. Please note that it is also an origin for kerning classes.
Just reporting this as a bug.
Thanks and Happy Holidays!!!
