VUDU search and filmography

[Rodney-2187]

I have a few titles in my library that don't show up when I search for them. For instance if I search for The Abyss, the James Cameron Ed Harris movie does not come up. If I bring up Avatar, click on the cast and crew and look at James Cameron's filmography, The Abyss is not listed. It's the same if I do a search for Blade Runner or look at Ridley Scott's filmography. I actually have The Abyss, Blade Runner: Final Cut, and the theatrical Blade Runner (with narration) all in my library and am able to watch them. I just have to scroll through my collection to find them. I did the searches on my computer and on the PS4 app. Are these movies hidden for some reason? Am I doing something wrong? If I didn't already own them, how would I purchase them now? Are there any other hidden titles?
