In bars 22 and 24 the L.H. sets of markings – consisting of a staccato dot and a slur – could have been added by Chopin to [A] after FE had already been engraved. It is less likely that they could have been added by Chopin to FC, since they are not characteristic of Chopin's additions.
The absence of the dots in GE most probably resulted from an oversight (or perhaps they were ignored? – both are very small) by the engraver.
Similar situations are to be found in bar 28 and in bars 118, 120 and 122.
