FE1 overlooks the 
raising f to f
at the beginning of the bar. In FE this note is placed on the lower staff, hence the error also affects the 4th L.H. semiquaver. This layout was applied in other sources as well, except for GE2 (→GE3) which placed the R.H. part on the upper staff throughout, as in our transcriptions. This resulted in before the 4th semiquaver being necessary only in the impressions of the 2nd German edition.
