Multiple instruments Layout problem

Hi ,
I am working on a musical Score/Piano reduction for a publisher in Berlin .

The MD/Conductor playing various keys,so I created a solo player with Piano,Celeste,Keyboard and Harmonium.

I added Chord symbols ,which show up on all instruments.
When I do a reduction MD/voc part theres always a empty Harmonium stave with rests and Chordsymbols ,which keeps showing up even if I turn on Hide empty staves…
Is there a way to define ,where Chordsymbols going to show up ?

cheers,

HJB

Check what you have chosen in the Chord Symbols section of the Staves and Systems page of Layout Options. If you’re trying to show chord symbols between the staves of grand staff instruments, you can’t also hide the lower staff belonging to that instrument.
