Thanks for the replay, I am sorry I could not see it in the details panel on how to change the name of each channel as you can see in the picture. When I click them it doesn’t do anything and when I Right-click the mouse it shows copy and paste.

I am using 4.23 now, do you think there is something to do with that?
