TV Go - shows that should be downloadable aren't
 

Tonight I set up the TV Go app for the first time, and I wanted to download some shows to my phone to watch. I went to the section that shows the downloadable shows, but some of them aren't actually downloadable.

For example, Friday Night Lights showed the download icon, and I could download it. However, Killjoys episode 1 didn't have the download icon, despite being in the downloadable shows category.

Is this a bug, or am I doing something wrong?

Nothing I want to download ever has the download icon - have to say this is a useless feature in my opinion.
