How to change Badges. I change Title badges but icon badges not change.
アバターに表示されているのはバッジではなく、アバターフレアです。これはグループレベルで設定されています。
You mean flair. 
@Bank_Live it’s because the flair is the primary group that you are in.
You just wasted seconds of my life that I will never get back with that unnecessary pedantry. 
I find it’s always a stellar idea to correct someone who is helping. I’m pretty sure the point was conveyed well enough to find a solution.
Thank you very mush.
