1.7 Random Letters Appears

[Magatsu-Iz]

In 1.7, when I change my identity, if i quit the game, my name gets a random letters in color red attached to it, and i cant remove it. Also in the top left is the same letters, it also appears in the place where the countdown to starting the gane appears.

Edit: It seems to only happen when I have the anti ban option on
