..

In FE1 (→GE1), in the version with 4 flats in the key signature, there is no  lowering G to G. It is probably an oversight by the engraver of FE1 or by Chopin himself in [A]. The flat was added in GE2 (→GE3).

In GE there is no  restoring f on the 3rd beat of the bar. The patent mistake was committed already in FE1 (or perhaps even earlier, in [A]), which is supported by the fact that no space for this accidental was provided for in FE. As it is already in FE1 (→FE2EEW), it must have been added in the last stage of proofreading this edition.
