Generating precomposed fractions

I followed the fractions tutorial, and get wrong metrics when generating precomposed fractions. In the second row an example build with the fractions OT feature. What went wrong when generating


Where do you see that? In Glyphs or with the exported font (if so, what format)?

In Glyphs 3 latest version

Can you send me that .glyphs file?

Any reason you have automatic alignment disabled in font info?

Yes. It is a pure components based type, the modules wouldn’t fit as wished if aligned automatically. But thanks, I forgot that for the prebuild fractions it is necessary.
