@Anonymous User Welcome to the community.
Sounds like you're not currently picking up COM5 and 6 on the transmitter you're tuned to. It's possible you have several transmitters in your area, and one or more of them doesn't carry COM5/6 (or has too low power).
Check to see if there is any maintenance work or faults on your local transmitter

as it's possible routine work on your local transmitter might mean they're not transmitting COM8 or have reduced power, particularly over theweekend, if that's the case there's not much you can until the work is completed.
If it's still not working properly today keep doing a few manual rescans from the Settings menu to see if the box picks up the correct transmitter (sometimes you might be asked during the rescan which transmitter you want to tune to, if it does then pick a transmitter that carries COM5/6, but if it doesn't ask you you'll just have to keep trying again).
