The seasons of episodes seems to be wrong. They don't even match what is described in the "media" section, nor the actual discs themselves. Most websites have the same list as Wikipedia, but I assume you all just copy/paste each other. The DVDs have season 1 & 2 together in Volume 1 (22 episodes), but you put them all in season one of your list (even though your prose matches the DVDs). Volumes 2 & 3 are what the DVDs say are all episodes of season 3's 50 episode season. Your list has the first dozen or so episodes of season 3 as season 2.
This site seems to match what the actual DVDs have: https://culttvman.com/swampthing/sw2.html
