Hello,
I see you have some special characters in your name. Do you have any special characters in your second account's name, by chance? Can you show a screenshot of exactly what your second account's name looks like?
Thanks!

It may be because of the apostrophe. You're not supposed to use any kind of punctuation in usernames. Most such characters will simply not appear, rather than censoring out the whole name, however. Are you continuing to experience this issue? And more importantly, are you experiencing this issue in other game modes, other chats, and other areas? Is it causing your account a hardship, or is it just a minor, trifling annoyance?

If the latter, than I would suggest simply ignoring it, since it's not causing any harm.

EDIT: OK, I've talked to the CS team, and they've told me that the reason this is happening is because of the apostrophe. Changing your name should fix the issue.

Edit: I've also deleted your picture. Try to avoid putting up sensitive information like your email address.
