"This channel does not exist"

Getting a wrong channel page when I click on the name of a channel within the “meta box?” in a post. When the link takes me to YouTube it says “This channel does not exist”.

I could put in the channel name but the link seems to want to go somewhere else. If I enter as one word it splits it up.

Can you give me an example of which is a channel name and which is a channel ID?

So I can be sure I am filling this out properly in the channel section?

Examples of what goes here
“Add a new channel or playlist:”

And what goes here
“Name: Channel/Playlist:”

would be helpful. Thank you.
