Channels DVR app and Guide issue

Im a new subscriber to Channels dvr and have installed the remote Channels DVR app on firesticks. For some strange reason that I dont all channels are not showing up when I'm on the Guide view. Only a set of channels show up. On my mobile it shows up just fine.

Maybe the guide is set to Favorites on the top left

Thank Aman. I will take a look later on tonight and will post result.
