I tried deleting the .numr glyphs and making them from scratch, but whenever I add “one.lf” as a component, it automatically adds it as a smart variable component. What should I do? I also can’t seem to “un-smart” the component.
You need to disable the “Regular” masters in the smart glyph settings. Because smart components can only have one master per axis. And then it seems to work as expected. But the slider positions are not right.
