I evolved for espeon with my buddy Eevee with 10km walk distance during the day and ended up with a Flareon. I took a screenshot and then moments later the distance regressed. Sadly the Flareon didn’t regress to an Eevee though. So just a warning to others there’s some sort of distance tracking bug and if you’re evolving Eevees perhaps go a decent amount over 10 km to make sure you get what you expect.
