You’d need to back that up with the code you used, or better, a minimal 
example. I’m having no problem with

%%%%%%%%%%
\version "2.19.35"
\new PianoStaff <<
  \new Staff = "foo" <<
    \time 7/32
    \key fes \minor
    \new Voice = "soprano" { \voiceOne bisis'32.. }
    \new Voice = "alto" { \voiceTwo a'\breve*49/64 }
  >>
  \new Staff = "bar" <<
    \time 7/32
    \key fes \minor
    \clef bass
    \new Voice = "tenor" { \voiceOne bisis32.. }
    \new Voice = "bass" { \voiceTwo a\breve*49/64 }
  >>
