The accent visible in A has a typical form of long accents. In spite of this, in FE it was reproduced as a short one. The sign in EEW1 (→EEW2) has to be considered to be long, yet the coincidence with the notation of A is most probably accidental. The omission of the accent in GE may be considered to be an oversight, however, it is surprising that the sign is absent in both versions of GE, particularly considering the fact that the same applies to 
in the next bar. Therefore, both indications may have been overlooked already in FE and completed in the last proofreading.
