The deletions of the 1st note on the 2nd and 4th beats of the bar, visible in A, suggest that Chopin hesitated whether to write these notes as big or small. The result of these corrections is not entirely clear (particularly on the 2nd beat); however, it seems to be more plausible that it concerned the transition to small notes, as it is in FE and EE.
