Year range Hong Kong Phooey

Currently, the year range for Hong Kong Phooey (https://www.imdb.com/title/tt0070996/reference/) is listed as 1974-1975. 

However, as you can see, all episodes on IMDb are from 1974.

Epguides.com also states the series only ran in 1974: https://epguides.com/HongKongPhooey/

And just like IMDb, Toonopedia also says it started on September 7th, 1974 and ran for 16 episodes: https://www.toonopedia.com/hongkong.htm

Can a staffer fix this please?
