So basicly,i went to comment and youtube showed the "Full Name" screen."Do you want to use you full name?".I clicked next and clicked "Keep using my youtube username".But,my profile picture has been removed,and my name seems be ok.

However,when i go to my settings i see this:
Account information

What does the highlited thing mean?I dont want to lose my username,as it would ruin me on youtube.I also get this on youtube:

Do i press the button highlited in red?

Never mind,i solved the problem
