Year range Josie and the Pussy Cats in Outer Space

Currently, the year range for Josie and the Pussy Cats in Outer Space (https://www.imdb.com/title/tt0068088/reference/) has a year range of 1972-1974. 

However, as you can see, all episodes listed on IMDb are from 1972: https://www.imdb.com/title/tt0068088/episodes/?year=1972 

themoviedb.org also only lists episodes for 1972: https://www.themoviedb.org/tv/24211-josie-and-the-pussycats-in-outer-space/season/1 

Apple TV has 16 episodes listed, all with a year of 1972 attached to them: https://tv.apple.com/us/show/josie-and-the-pussycats-in-outer-space/umc.cmc.m3ufgliheaudzxxan7cngmvw 

Can a staffer look into this and correct the year range please?
