Year range The Kwicky Koala Show

Currently, The Kwicky Koala Show (https://www.imdb.com/title/tt0255738/reference/) has a year range of 1981-1982. 

However, all episodes listed on IMDb are from 1981. 

Moviefone also states the series only ran in 1981: https://www.moviefone.com/tv-shows/the-kwicky-koala-show/jSLOXZFg3Wq88NHNUYa36/ 

The same goes for TMDB: https://www.themoviedb.org/tv/10333-the-kwicky-koala-show 

Can a staffer fix the year range please?
