Tag Change

Hello Discord, I came to post about a bug that got me a flea behind my ear, Well let me start as it all happened. It was at dawn talking to friends, I changed my name to "Maximus", and suddenly, my tag changes without having the signature of Discord Nitro, it was very strange that it happened and I was very moved by that, after that I was thinking about it and I decided to report this error, because it was very strange, and then I decided to post this for you. there is my story behind my complaint, if you answer me I will be very happy with this. :)
