Issue with a Lifetime TV Movie series

So, I've just discovered a problem (which I inadvertently added to). Last Sunday (July 14), Lifetime premiered a TV movie called "Lies and Ex Wives: Secrets on Maple Street". IMDb originally had it listed as "TV miniseries", and at the time I didn't know any better so I had it moved to a "TV movie" entry title. Well, it turns out, this Sunday (July 21), Lifetime is premiering "A Family Nightmare: Secrets on Maple Street", and next Sunday (July 21) Lifetime is premiering a movie called "Murder for Mortgage: Secrets on Maple Street". Currently, both of these are listed on IMDb as *separate* "TV miniseries" (i.e. different entries). So, in fact, all three of these should be listed under the title "Secrets on Maple Street" as a "TV miniseries", with "episode 1" being "Lies and Ex Wives", episode 2 being "A Family Nightmare", and episode 3 being "Murder for Mortgage". The question is, how do I make that happen? Or is there a way I can ask for admin help on this? Thanks in advance.
