I haven't seen anyone else mention this but I have played a number of scenarios and services now and the overview levels has not changed. It seems to be registering these correctly (the medals) but the level and points have not changed. I am guessing the -1 is a problem. Maybe a profile import problem (PC Steam) although the data imported (miles, level etc.) appear to be correct.
What you should be seeing in that screen are your level with your favorite train and your level with your favorite route. Since you imported your profile, your favorite train and route are probably part of one of the old TSW2 DLCs that will come to TSW3 september 6th, and cant be shown right now because you do not have them yet.
