[update on the issue of zero start odometer]
With helps from users, especially from Glenn, the mystery of the problem is clear now. It turns out that users who don’t enter vehicle name in the log are affected by this problem. Version 1.7 was handling the case, but that was broken in version 1.8. I’m going to fix the bug as soon as possible, and it will be available in the next version 1.8.6
