The easy test for this problem is to first engage the sostenudo pedal and 
then, one by one, play each note hard.  Also, if your damper pedal travel 
is excessive/not limited and the upstop rail is too high, you can (at 
least) jam the tabs against the knife, or flip them over... and there they 
stay.
