Kevin, I just happened to have this happen to me too. It just came up as the "Pick 4" style out of nowhere. (I tried it, but prefer the head to head as well.) Look to the right of the screen, under "Who Will Win" in the black area, kind of across from the window that holds the channel you're viewing. It says in red, [Switch to Head to Head Judging] or whatever they call it. Click that and you're good to go.

A musician must make music, an artist must paint, a poet must write,
if he is to be ultimately at peace with himself. What a man can be,
he must be. -- Abraham Maslow, American Psychologist
