The slur over these bars exists only in GC in bars 573-576, which here are repeated with a change of the beginning. Since the slur in GC begins in b. 604 on the previous page on the last chord. A question arises here how to connect this slur with a slur over the four-bar section in 605-608. We assume them to be one slur, and as such it is the copied in GE2 (in GE1 there are no slurs in bars 604-607, which is an obvious error. However, another solution may be proposed here where only bars 605-608 are slurred and the slur in b. 604 ends on the sixth beginning in b. 605.
