The missing c1-e1 third, ending the phrase of the orchestral part, is most probably a mistake of the engraver of GE. It could also indicate that it was added in the last proofreading of FE, yet the engraver's mistake is supported by the placement of the Solo indication in GE, i.e. only just over the 2nd beat of the bar, probably due to this third, which does not belong to the solo part.
