Incorrect End Date Showing for TV Series

The end date of the TV series “All the Rivers Run” [tt0086663] is currently showing as 1990. This is incorrect - the series was released in its entirety in 1983, in Australia. A sequel “All the Rivers Run II” [tt12312522] was released in 1990, but this has its own title page on IMDb, so its release date should not affect the entry for the original series. Please can this be amended? Another issue with this title is that a release date of 10 October 1983 is showing *at series level* which is not correct, as the series was first shown on 4 October 1983 in Melbourne, and both this date and the later Sydney transmission date appear under Episode 1.1. The later date was probably entered when the page was created, before episodes were added to it. Can this be deleted please as it is misleading, and unnecessary? Many thanks CaptainSiCo ✈️
