The slurring of the first phrase in this section is inaccurate or erroneous both in FC and FE. It concerns particularly FC, in which, when interpreted literally, the slurs are unclear and almost certainly incomplete. The slurring of FE can be easily guessed, as a result of which a corrected version of this slurring is already present in EE; in this situation, it is the version we give in the main text.
The slur added in pencil to FC in bars 27-28 comes from the reviser of GE, who considered the absence of a slur in these bars (and actually rightly so) to be a patent mistake (in FC these bars end the page, which is often conducive to oversights).
