As was the case in b. 3-4, in A Chopin generally omits accidentals next to the bass quavers if the accidentals have been written an octave higher next to one of the preceding semiquavers. In the discussed bars, it concerns G
in b. 14, B in b. 15-18, f in b. 20 and g in b. 21. That notation was literally repeated in FE; FC repeated it almost without changes (the only addition was a 
next to B in b. 16). EE1 added the majority of the necessary accidentals – all except for the of G in b. 14, while the remaining editions contain a fully correct notation.
