I had something like that happening in a Tour not long ago. See the last part in the following post.
My suspicion is that it’s possible to fiddle with the results via a mod menu or so. Did you maybe had a “fishy” player in the team that could have done this?
It could of course also be a bug but I never had something like this happen before the last update. If it really is just a bug then it must have been introduced recently.
