Show with no upcoming episodes doesn't have Pass on AVTV

My wife asked me to set up a season pass for a current show that is off air until the end of March (so doesn’t show upcoming episodes in the guide).
In the ATV interface it didn’t offer a season pass option, but did in the web interface.

Is this by design?

Not necessarily, but since everything is based on the two weeks of guide data available, it is the expected behavior right now.

I’m not sure I understood this correctly. Are you saying you can’t create a season pass for the show by searching for it on ATV? But the same works on web? That is definitely not expected.
