YouTube Season/Episode presentation
What you are referring to is called a series playlist. A series playlist is used to display videos in that manner. 

What you have misunderstood is that it's actually the name of the show that is displayed before the "S11 E80", although I understand that it is confusing when the show has the same name as the channel.

This feature is easily utilized, it is however required that you have a verified channel. If you do, you should easily be able to add a series playlist from the playlist menu in the Youtube studio.

Best of luck
