SE1EP1, cast aggregates out to Series' umbrella page?

Hello hello,

Re "Allen v Farrow" HBO series..

https://www.imdb.com/title/tt13990468/reference

I'm not seeing Woody Allen credited at all..

I saw a similar issue with Netflix series, "Don't F*ck With Cats," where a series' main page doesn't list a Cast / personnel as (Himself archivalFootage), yet said person might be listed on the page for explicitly Se1Ep1.

What's the policy at play here why the Series main page isn't the super-set of all humans appearing across all episodes?? Thanks!
