No indications in AI

The way in which the  indication is written in A makes a misinterpretation highly likely. Due to this fact, in the main text we give preference to this version. Apart of the change of  to  in FE (→GE,EE), the ten. indication for the chord in the L.H. was omitted (the indication for the R.H. was reproduced in accordance with A), which reinforces the conviction about the engraver's inattention.

Lack of a separate ten. for the L.H. is most probably a result of an inattention of the engraver of FE (→GE,EE).
