First of all, I log in with the account fd, and I can log in normally.

Then log in and the account will automatically become fd1

Use fd’s account to log in, but the information shows that you are logged in to fd1, and then you can still see fd’s account

And the amazing thing is that the account names displayed by fd and fd1 are both fd (the account name is not the user name, I have changed the user name to a Chinese name)

I didn’t change my account name or avatar, it was just two accounts, but I clearly logged in with the fd account, why did it become fd1? Help! ! !
