FE has a C
(with a 
) as the bottom note of the semiquaver. It is either a revised Terzverschreibung error or a mistake resulting from similarity of the orchestral motifs in this and the previous bar (in GE1, being the base text to FE, both bars are printed next to each other, in one line). EE did not repeat this mistake (cf. the note on the clef).
