How Can I Change My KI Forums Username?

Can any of the community Moderators help me? I updated my Gamertag from SaltBomber44 earlier today, to TEK | kazamastar. Help on updating my KI Forums username? (Attached is from the Xbox Beta app)

I believe you need to log out and clear your browser cache for it to update.

Thanks (tho it displays it without the space lol)
