  b. 19-21

g1 & c2 tied in FCI

g1 & c2 repeated in A (→FE,FCGE)

g1 (quaver) & c2 repeated in EE

In the version prepared for print, hence the latest one, Chopin abandoned the ties to g1 in b. 19 and c2 in b. 20-21, since nothing suggests that respective ties could have been overlooked.
At the beginning of b. 19, FE omitted the rest in the lower R.H. voice, and the dot prolonging the crotchet g1. The EE version of the first half of this bar could be an effort to correct this unclear notation. Interestingly, traces of a deleted beam encompassing the first half of b. 19 are also visible in FC.
