Hello @jimmy mack
Thanks for your question, this has happened to me a few times, there are times when the Truckbook is out of order for a moment, otherwise, if this is not your problem, remember that the Truckbook counts the kilometers by the speed at which you go If it is in the [ATS] you will need to go 130Km so that I can tell you well and in [real], and in the [ETS2] it will be 110Km, if you don't go at this speed I will count them as [race].
I hope I can help you in your question.
Greetings,
AldoTruck.
