Alright, I had a look at the file and ran into the same issue – it’s hard to say where exactly it occurs, but it has something to do with the variable font origin. The instance that has the same coordinate(s) as the variable font origin (the Light master in your case) receives a new instance name “Regular”, or whatever else you define in your variable font setting. To an extent, this makes sense, as the style name of your variable font is Regular, and this optically is represented by the Light, so it makes sense that it is not called Light.
To fix this, simply do the following:
Add a new variable font setting. Set the name of the instance to whatever you want the instance at your variable font origin to be called – if you set your variable font origin to Light, name your variable font setting Light, accordingly.
Bonus: Add a parameter to the General section of your variable font setting: Localized (Localised!
) Family Name. Enter something like “Engrace Variable”. This way, you can install your variable font and the static instances side by side.
Otherwise, it would be good to check the settings of your metrics (ascender, cap height, x height, descender), as well as their zones. The ascender is on some other planet
