Hi! Sorry this is way later than I said it would be, no excuses I am just bad at prioritizing my time.
I just pushed a fix for the ä/å bug and also the i/n kerning but (small regular also had this error). Can you re-download and tell me if it is fixed for you? Reminder: if the font is in your OS font library, you may need to uninstall it manually before re-installing the font to get the OS to respect the new version (I don't know why this happens or how to fix it).
Thanks!
