Wrong dates for series stars

I was browsing some entries and I noticed that the entry for Bill Mumy claims that he was on the original "Lost in Space" series from 1965-1993.  The series only ran from 1965-1968 and if you go to the series' page, this is clear - there were no episodes after 1968 until the reboot in, I think, 2018. The 1965-1993 dates for Bill Mumy are CLEARLY wrong. The odd thing is, if I look at the other stars from that series, on the seris page (https://www.imdb.com/title/tt0058824/reference/?ref_=ttep_ov_bk) you can see that the main stars: Guy Williams, June Lockhart, Mark Goddard, Marta Kristen, and Angela Cartwright all show the same years: 1965-1993.

This is likely due to the series original pilot having been aired somewhere on some channel in 1993. But, that episode was made in 1964, not 1993, and showing it as 1993 is just plain WRONG. The fact that it aired somewhere in 1993 shouldn't be relevant.

I don't know how to correct this, and I don't know how to contact someone who can. But, this is a HUGE mistake. Like I said, the episode was filmed in 1964. It was seen by test audiences back then. Its first airing, technically, was NOT 1993. But, even more obviously, Bill Mumy and the other stars weren't on "Lost in Space" from 1968 all the way through 1993, and listing it that way is misleading and wrong.
