The missing c3 note in GE (→FE,EE,IE) is most probably an oversight by the GE engraver. In Chopin's autographs, establishing the presence of a middle note of a chord on a ledger line can be problematic; in this case, however, the c3 notehead is very clear, even bigger than e
3 (however, the presence of e3 is proven by the very fact of writing a ledger line at this pitch).
