Generate kern feature automatically is not working [2.6.4 (1282)]

Hi! For some reason Glyphs doesn’t generate kern feature. If I add it manually and click “generate automatically”, it just deletes. Exported OTFs have kerning, but variable fonts don’t. Am I missing something? I believe it used to work fine.

Also, as far as I remember clicking “update” usually generates some basic features, but nothing happens now.

The kerning feature is always generated on export only. You don’t need to care about that.
