Changing Season numbers for a series

During the past couple of years, I have been watching the first 25 seasons of the German TV series [link=tt0077076]. As there was a mismatch of the season numberings, I have corrected them while providing individual data to each episode of the series. I won't be continuing watching the series. Starting at season 27, each of the following seasons is actually one number down to the listing on IMDb. Season 27 is actually season 26 etc. until the series ends with season 45 (not 46). Is there a way to change this wrong numbering without changing every single episode individually?
