I have similar issues, not just for MB 45, but also at least MB 30, MB 44, and MB 67, which are some of the higher-numbered routes I've clinched. It seems to affect all routes 25 or higher, and few or none with lower numbers, with some exceptions such as MB 75, MB 83, and MB 101 (which, coincidentally or not, started off in the cansph set). So it's not just 7/8, or MB 45.
In addition to the problems 7/8 reported, the affected routes don't show up in my log file. I haven't yet tried to check (too tired right now) whether my mileage from the "missing" routes is omitted from my MB total, or whether the total mileage for those routes is left out of the total for all MB routes.
