In the 1st chord in A (→FE1→GE1,EE3) there is no cautionary 
before g2, although a relevant accidental is written in the L.H. The sign was added in FE2, as well as in GE2 (→GE3→GE4) and EE4.
A cautionary was added before f1 in the 5th chord in FE1 (→FE2,GE,EE). In addition, in FE1 a raising B
to B was added, certainly by mistake. The latter was removed in FE2, GE and EE.
