Sources not Consistent?

I have two Apple TV’s in my house. I have several custom m3u sources (TV streams). On one Apple TV, the channels show up just fine (they say four channels found in settings - the total amount in the custom list) but the other Apple TV says found 0 channels and none show up. I’ve tried restarting the offending Apple TV and force quitting the app to no avail. I’ve also tried removing and readding the custom sources as well. Any ideas on how to make it work?
