In A (→GC,FE1→FE2) there are no accidentals before the last chord in bar 68 and in the entire bar 69. Moreover, in both previous FE there are no flats before two topmost notes of the chord at the beginning of bar 68 (d
2 and e2). In FE3 the missing signs were completed, apart from the 
lowering d2 to d2 in bar 68. GE and EE have the correct notation, yet only in EE there are all flats before the second chord in bar 69 (the rules of the signs validity with the use of an octave sign were not established).
