Season 18 isn't supposed to be Pokémon The Series: Sun and Moon, it's supposed to be Pokémon The Series: XY Kalos Quest. I think you need to double check every season and every episode and make sure they're correct. It'd also be nice if there was a total episode counter in the list of episodes for when the overall episode number goes into the hundreds, such as episode 6 of Season 18 being episode 849 overall, just put the episode number of that season like normal, but add, in parenthesis (849) just so it's easier to track down specific episodes instead of having to go episode by episode and get thoroughly confused by the episode names, which is another thing I think you should fix
