True Entertainment Just Showed The Cybernauts With Wrong End Credits

Just watched season 4 ep 3 Of The Avengers THE CYBERNAUTS with Michael Gough, Fredrick Jaeger, Burt Kwouk, Bernard Horsefall, John Hollis & Ronald Leigh Hunt, Which Was A Excellent Episode but I was surprised when I watched end credits to see None Of Them Mentioned Instead It Said Patrick Cargill, Suzanne LLoyd, Noami Chase, Peter Bayliss, John Woodvine etc & I Just Looked At IMDB Ep Guide And They Were All In Season 4 Ep 7 THE MURDER MARKET.

I have BT Vision and Just Rang Them And Person There Said He Would Make A Note For Someone To Contact True Entertaiment About The Mistake But As It Could Not Be A Mistake From Original Showing In 1965 As The Murder Market Was 4 Episodes On From The Cybernauts How Could Such A Cock Up Possibly Occur?

Makes Me Wonder When True Entertainment Shows THE MURDER MARKET Will It Have End Credits For THE CYBERNAUTS Or Not?

I Have Seen Thousands of Mistakes On Movies & TV Series Such As A Stained Glass Window
In THE VIKINGS 1958 400 Years Before They Existed etc But This To Me Is Number One Greatest Mistake Ever.
