Wrong year range Wacky Races

Perhaps it has to do with the non-existing episodes that have been added to this title in the past (see https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/nonexisting-episodes-for-wacky-races/65d5e26e25c30b3e7cebeee2) but the year range is wrong. It says 1968-1970, but it should be 1968-1969, as evidenced here: https://www.imdb.com/title/tt0122365/episodes/?season=1

Can a staffer fix this please? Contributors can't fix this themselves.
