Season updates reversed on title?

https://www.imdb.com/title/tt32085850/episodes/

I've been working on this show, on and off, for well over a year now. It's almost certainly the most difficult show I've had to do, as it was an early morning schools show (so often limited listings in newspapers), ran for over 20 years, and had MASSES of repeats. Some years they'd show just one new episode, the rest reruns.

I'd been sorting out, and I have an Excel spreadsheet to help me work it out correctly (nerd).

Yesterday there were 34 seasons on there - like I say, it ran for over 20 years - but today it's down to 18.

If people are going to undo my work, it's pointless me doing it in the first place.  There are 189 episodes on the title, and I added masses of them myself. If my plan for a proper structuring (which will take some time) is going to be undone, I might as well stop right now as I'll be wasting my time.
