Unity Engine

Hey everyone,
I’m Knuffy, a Indie-Game-Dev with the following problem:

I changed my avatar at the forum to the pictures you see on the left but I can’t see it everywhere else.
There’s always the same standard avatar with my beginning letter.
So, does it is normal or shouldn’t it be like this?

Thanks you very much, I hope you can help me.
xoxo,
Knuffy

And is there a option to make Unity in a fullscreen mode? Thx!

It’s normal ig, I can’t change the other avatar either.
