In A and in the remaining sources there is a cautionary 
next to A in b. 47. In the main text we add in this bar a also next to a. The accidental was also added in FC (→GE). In addition, since in FC (differently than in A) b. 48-49 were marked in an abridged manner as repetition of b. 47, GE printed the cautionary naturals next to A and a (present in FC in b. 47) also in b. 48-49. All those cautionary naturals (including the unnecessary ones) were also introduced in EE2, most probably on the basis of comparison with GE1.
