Direct Password Input On Log-on Screen?

Why doesn't the logon screen show me my account with the password input field already availible? It used to, because I only have one account on my laptop and so whenever I turned it on or when it woke up from sleep, the account was already selected so I could just entered my password. Now the Switch users button has appeared and I have to first click on the account so I can then input the password. I found the solution to disable then Switch users butto, but the account still must be clicked first, as if there were more accounts on the laptop.
