The A (→GE) and FE1 version is probably Chopin's mistake – the chord is written there in bass clef, while with a greater number of ledger lines, Chopin would relatively often write one too many or one too less. This assumption is confirmed by the changes introduced at the stage of proofreading FE2 (→EE), almost certainly at Chopin's request.
