Exporting Names

In which app?

Generally, Windows only considers the Regular-Italic-Bold-BoldItalic combo a family. Read the section about style linking in the handbook, please.

last thing i did was entirely disabling all style linking.
so thats not the issue, however all weights installed on windows 10 are named lighter than intended

its in ms word for example
but also visible in the font manager fontba.se

Can you send me the .glyphs file please to support (at) (this website without www). I will have a look.

done

When you disable style linking, make sure the of: field is empty:
