Time signature and acciaccatura

If printed alone, the two parts of Flutes and Trumpets are ok, but if I
merge them into a score the result is ugly.

%--------------------%
% PART: Flutes, OK IF ALONE
%--------------------%
\version "2.18.0"
PbMusic= {
 % Bar 1 
\clef treble \key ees \major \time 2/4
 R2
  | % Bar 2
     \time 3/4 R2.
  | % Bar 3
     \time 2/4 R2
} 
  \header {
     tagline=""
     title="Test"
   }
% --------------------

\score {

   \new Staff = "Staff_b" {
        \set Staff.instrumentName=#"Flutes"
        \set Staff.shortInstrumentName=#"Fl"
        #(set-accidental-style 'modern)
        \PbMusic
     } % end staff
>>
\layout { }

This is the part of the trumpets:

} 

  \header {

        #(set-accidental-style 'modern)
        \PdMusic
