Scene Graph - Disable Controls in Live Stream

Hi, could anyone help explain to me what determines whether I have FF/REW, Instant Replay and Left/Right controls when playing a HLS file that is a live stream?

If I set the streamformat and url attributes in the Multi-Live Scene Graph sample channel it seems to work correctly and disable the controls during playback. However I have a channel built off of the Hero Grid sample channel and I'm struggling to disable the FF/REW, Instant Replay and Left/Right controls.

Could anyone tell me what I'm missing?

Thanks
Zach
