Why are some steam games not imported?

[Darkcloud]

So like I said in the Title Launchbox does not find some Steam Games in my library. The first time I noticed it was with a game without a Store Page yet but now I also have some that it just doesn't import. My guess is that there is not much that can be done other than manually add those games through the launch URL but what is the reason that they are not detected?

Can you give an example of a game that's in your library that was not imported?  Might help someone to provide and answer if we had some examples
