It is unclear whether according to Chopin diminuendo in these bars was supposed to be divided in two sections or not. In GC and CDP, bar 13 opens a new line of the text, hence it was most probably the same in [A]. In such a situation, two subsequent  or  signs were treated as equal to one, longer hairpins in Chopin's times. As two out of three sources based probably on [A] (GC and EE or FE) have divided signs and only one (CDP) – combined, in the main text we adopt the first notation.
However, most probably these bars, independently from the notation, are supposed to be embraced with one diminuendo wave, as it was unambiguously indicated in analogous bars 31-32.

It is unclear, which length of  corresponded to the last Chopin's intention. Compatibility of AW and GC (→GE, inaccurately) suggests that GC may include an earlier version, changed by Chopin in the remaining Stichvorlage manuscripts. However, the presence of the longer sign in CDP, generally compatible with FE (and to a lesser extent with EE) denies this interpretation. Perhaps the concurrence of AW and GC is accidental and the sign could have been inaccurately copied by Gutmann.
