Not Getting Ion Life, Qubo, and Other Local Channels

I'm currently using the Xfinity Beta Streaming on both PC and Roku and it does not show some local antenna programming:

11.2 - Kare WN (Court TV)

23.4 - Get TV

41.2 - Qubo

41.3 - ION Plus

41.4 - Ion Shop

I'm wondering why these aren't showing up and now to go about getting them to.

Thanks!
