Easiest fingerings missing? – U-Chord Review

I must be missing something. You don’t show the simplest fingering for A-minor. Everywhere else one finger on the second fret of the G string is a A-minor. Or are you just assuming everybody already knows the most basic fingering so you don’t have to show it? Makes me distrust all your other fingering options. Or seriously, maybe I am missing some setting?
