Redundant login

So the login for this game is redundant and there may be an additional problem. So I have the “Remember Account Name” box checked @ the login page. So here’s the steps I go through to login to the game:

  1. Start WoW-Classic
  2. Select a Realm from the list
  3. Type in my login information
  4. Select a Realm again (redundant…)
  5. Choose my character

Now @ step 3, if I only type my password, it will send me to the Realms list… However, after choosing a Realm after only typing my password, I’m sent back to the login page (step 3). So I have to type in both my account name and password to log in. And no, my account name is saved correctly (else how would I have gotten to the Realm list from the login page if it wasn’t correct information?)
