It is hard to state how the difference in the rhythm on the 1st beat of the bar occurred. The dotted rhythm in GC (→GE) seems to be a mistake of the copyist – the text is written uniformly, moreover, only bar 7 is written out with notes, as a result of which one, possible, mistake could have contributed to the change of the rhythm in both bars. On the other hand, Chopin's proofreading cannot be entirely excluded (a similar situation appears in Allegro de Concert, Op. 46, bar 17). In this situation, in the main text we give the version of FE (→EE), compatible with the unquestionable rhythm of analogous bars 11-12. Rhythmic variants of this type are to be found in numerous works by Chopin.
