Unable to remove Guest user. Guest user is asking for password and is glitched.

I turned off guest user on my mac. But it is glitched somehow and is still showing on the login window. If you try to click it then it asks for a password(Guest users doesn't have password). I have already tried turning on/off guest user.

Is there any way to remove this ?

And now if I try to turn on guest from settings then I get two guest users. One is normal but the other one asks for a password
