From the harmonic point of view, the four-note chord in PE is absolutely possible. However, the natural character of voice-leading in the triad version of JC and EF encourages to suppose that the version of PE may be erroneous. The engraver of PE could have taken an accidental ink spill on the intersection of the stem and ledger line for a note. The half correction also offers food for thought: adding the right note without deleting the wrong one. Such situations can often be found in Chopin's prints, which stems from the fact that adding a new note head was technically much easier than deleting the old one. In this case, it is c1 which was mistakenly left (cf. bar 65). For those reasons, in the main text we adopt the chord without c1.
