A comparison with analogous bars 287 and 303-304 points to an inaccurate placement of the 
mark in FE (→EE). A corresponding correction was introduced already in GE. In turn, in EE, another mark was added at the beginning of the bar, which is both an arbitrary and incomprehensible revision if we take into account the compliance with the harmonic course, confirmed in the analogous bars.
