It’s all fine. I’ve just pointed out where the problems with Garmin lie. On the one hand, it’s the cloud, and on the other, it’s the route recalculation. As far as I’ve known Garmin, route recalculation has always caused problems, even without the cloud. That’s why many people display the track on screen to check it. Unless you’re planning a route from A to B directly on the device, in which case it doesn’t matter.
If you copy a track onto the Garmin device and convert it into a route on the device itself, it works well too. Unfortunately, though, a lot of information gets lost that way.
