This is the second of the places in which Chopin changed the melodic line of the Etude (cf. bar 28). The final version is present in Ap, it was also already written in the base text for FE.

In one of the last proofreadings of FE (→EE) a cautionary  was added before the 14th semiquaver a1. In this context the sign seems to be totally unnecessary.

Neither in CLI nor in Ap there are cautionary naturals before the 2nd crotchet in the L.H. Chopin would add signs at different stages of the Etude's publication preparations – before in the base text for FE, before in a later proofreading.
