In A there is no 
before the 1st semiquaver in the L.H., yet it is before the 6th note. However, there are no doubts that both notes are meant to be b. The error was corrected in a proofreading of FE, by moving the at the beginning of the bar. Moreover, the 
before the last semiquaver (f1) was omitted in A (→FE). GE and EE have a correct text in this bar.
