Welcome to the Roku Community!
Can you please provide us with more specific information about the issue you are experiencing? I have a few questions to better understand the behavior you are seeing:
1. When did this issue first start occurring?
2. Do you observe this behavior while using any other channel(s) on your device?
3. Have you tried removing the channel, restarting your device from Settings>System>Power>System restart (If you do not see a Power submenu, skip to the next step), then once it loads up again, adding the channel back once more to see if that clears things up?
4. Are you using a Roku player or Roku TV?
With more detailed information, we will be able to assist you further.
