IMDb Support didn't add connections... so I'm wondering if someone here could confirm that these connections are valid.

IMDb Support declined my contribution to add these connections: Alan Wake II: Behind the Scenes (https://www.imdb.com/title/tt37870228) is followed by Alan Wake II: Dev Streams (https://www.imdb.com/title/tt33094163) and is then followed by The Actors Behind Alan Wake II (https://www.imdb.com/title/tt34878576). I'm wondering if someone here could confirm that these connections are valid. The response I received was "Bts and specials are just extras of a title which will be already part of the original title." These titles that I requested to be connected were released separately from the source (https://www.imdb.com/title/tt16385682) and are part of a collection of behind-the-scenes series' and should be connected to each other (note that I am not trying to connect these to the original title in this way). Could someone please take a look at this again? Thanks!
