Non-existing episodes for Wacky Races

AFAIK, there are 17 episodes of Wacky Races (as confirmed here: https://www.imdb.com/title/tt0122365/trivia/?item=tr6007878&ref_=ext_shr_lnk ). Yet, there are more episodes listed on IMDb: https://www.imdb.com/title/tt0122365/episodes/?season=1

In the original run, one episode consisted of two races/stories. It seems someone added some of those stories as separate episodes. Can these be deleted please and can the contributor(s) be contacted about this?
