The graphic difficulties, which the engraver of FE would have to face if he wanted to fit 
and sotto voce written in A, could have contributed to their omission. However, independently from the fact whether Chopin deleted these indications at the time of proofreading FE or whether they were simply not there, his decision to add 
must be considered as binding. In the main text we move this mark by one quaver, as the musical sense hints at the fact that Chopin's entry was misinterpreted.
