Incorrect Pokémon Seasons

[Houfino 43]

EDIT (9:50):Hi everyone,

I'm having a small problem that I still can't figure out. I have Pokémon Seasons 20, 21, 22, and 23 according to Wikipedia, and that season list is correct. I'll add the rest of the Pokémon series later once I solve this issue.

I added everything to Emby and let it scan the library. Now it's a complete mess. Instead of Seasons 20–23, Emby shows things like Season 18, Horizons, or Season 19.

I need Emby to display the correct season numbers according to Wikipedia. How can I fix this? Has anyone experienced the same issue?

Also, all episodes are stored in a single folder (Seasons 20–23 together). I don't have separate folders for Season 20, Season 21, Season 22, and Season 23.

Thanks!

EDIT (10:09): 

I managed to fix it, but I'm still having a problem with Season 20 only. Why is it showing Horizons? Seasons 21, 22, and 23 are correct. The issue is only with Season 20, which should be Sun & Moon.

How can I fix this?

Thanks!
