Year range Josie and the Pussycats

Currently, Josie and the Pussycats has a year range of 1970-1972: https://www.imdb.com/title/tt0065307/reference/ 

However, as you can see, all episodes are from 1970-1971: https://www.imdb.com/title/tt0065307/episodes/?year=1970 

The former Big Cartoon Database agrees with a year range of 1970-1971: https://archive.ph/20130118010916/http://www.bcdb.com/cartoons/Hanna-Barbera_Studios/G-J/Josie_and_the_Pussycats/index.html 

So does TMDB: https://www.themoviedb.org/tv/4489-josie-and-the-pussycats 

and classic-tv.com: https://www.classic-tv.com/cartoons/josie-and-the-pussycats 

Can a staffer fix this please?
