Just like in b. 34-35, Chopin changed the pitch of the 2nd and 4th notes in A from g1-f1 to b1-a1. In this case, however, the crossing-out of both noteheads also includes the stems (pointing downwards) of the separated quaver voice, which resulted in it having been overlooked both in FC (→GE1) and FE (→EE). Assuming a mistake, GE2 (→GE3) separated both notes after the previous bars.
