In FE1 there is no 
next to b2. Moreover, A (→FE1→GE1) has no before the first e1 in the L.H. It seems even that in A Chopin cancelled that sign probably considering valid the earlier in the R.H. Remaining editions have these inaccuracies corrected.
In the main text we omit the superfluous added in FE (→GE1→GE2) next to the last a in the bar.
