On Tom Welling page there is no way to correct a certain error.

This has happened because someone has added dates to an Unaired Pilot, claims in trivia say it was released on a Season 1 dvd in 2003 but the airdates are all between 2017 to 2021 for DVD releases in Middle East & Asian countries. I cannot find any evidence to corroborate those dates but there's some good investigators on here that might be able to.

In what I could find, some of these countries just had DVD imports from the UK rather than their own versions for sale.

It could be dates added just to troll fans who are seeking that grail of an episode or even to scam them into buying DVD sets at high prices from the person who added that data, could even just be a fanmade using the released version and deleted footage since some scenes were just reshot with a different actress playing Martha rather than a whole new pilot being made (bootleg original scenes have long been around: https://www.youtube.com/watch?v=A8dFQacmwV4), hopefully someone can get to the bottom of it.

If those release dates and that trivia cannot be verified they should be deleted.
