The missing slurs must be a mistake of FE, in which these bars are separated by the transition into a new line. When repeated a bar later, this motif is already provided with slurs, which proves the mistake, as a result of which corresponding additions were already introduced in GE and EE. See also the note above. A similar situation can be found in b. 195-196.
