In the available photograph of A, it seems that the mark entered under a part of the quaver figure is an inaccurate slur of the original range (only to the last quaver). The longer slur entered over the figure must be the final version (see b. 194-195), hence we give it in the main text as the only one, in compliance with FE (→GE,EE).
According to us, the possible slur could also be a 
mark, of which it is only the upper arm that is visible in the photograph (cf. in b. 200). Due to the uncertainty concerning the interpretation of the mark and its absence in the principal source (FE), we do not include it in the main text.
