Why would recording channel 4.1 record on 29.3

When I wish to record channel 4.1 the recording takes place on channel 29.3
Can you help me?

Do a channel rescan, and make sure to add the channels you want to the guide.

Due to the channel repack. Do a new channel scan, remember to hit “add to guide” once the new scan is done.

Is the same show on both channels?

No
Cant figure it out
