Got everything setup but have some questions

So I have the HDhomerun flex 4K integrated into my plex server. When I go to Live TV & DVR in Plex it says 47 enabled channels with 108 total. I did a channel scan in the HDhomerun gui then in Plex. Is this normal? Anyway to get more of the 108 total channels?

I appreciate any help and man the channels I’m getting are crystal clear with no issues!
