password reset

Hi I have a macbook pro and I tried resetting its password, and the password was reset but when I am entering the password the username is not accepting. When I am resetting the password the admin name there is my full name without any space. But as soon as I reset the password the admin username on the screen comes without space and is not accepting the password.

I've reset the password many times.

I am attaching the pictures check the reset password page where the username is shown without space and on the other page it is seen with space. Even thou I have just one user account.
