Lyrics and figured bass positioning

[Gilles]

Hello.

In the attached file, I want to stack two "PianoStaff" (each with their
own lyrics and figured bass lines). [See attached pdf.]
But I can't figure out why the lyrics and figures intended for the first
piano (setup in lines 58-59) come *after* the second piano. [And if I add
those to the second piano I get 4 lines below the second piano.]

I'm probably missing something obvious :-{

Thanks,
Gilles
