Yes, that part was not updated (yet). You could solve the problem by typing -1 as season. After a patch that I will hopefully make tonight it will even stay with the correct season after that, but at the moment you will have to retype the -1 each time. If you were promoted or degraded you can open the team list and doubleclick on your team name. That will updated the series for your team.
Quite convenient, right? ;-)
We tend not to think about season change related problems until they actually appear, unfortunately.
