The two-bar-long slur in FE (→EE) is most probably inaccurate – in bars 11-12 the same notation of [A] was interpreted differently, as two slurs. If the slurs in [A] had a similar range to these visible in GC, the engraver's doubts may be considered to be justified. At the same time, it is an indication that in bars 7-8 and 61-62, it is probably the slurs of FE that are inaccurate.
