Chord with c2 in A (→GE) & EE

Chord with a1 in FE

..

The version of FE with a tenth chord is certainly erroneous. The mistake was corrected in EE, most probably on the basis of comparison with analogous bar 46.

Sixth in A & GE2

a2 alone in GE1 (→FEEE)

The absence of the bottom note in GE1 (→FEEE) may be considered an oversight of the engraver of Chopin's proofreading – in similar bar 48, there is a sole aas the grace note.
In GE1, the head of the grace note is placed at the right pitch, but the ledger line was overlooked.
