You need to take care of "Repeat_acknowledge_engraver" and
"Volta_engraver" as well.

try to replace \score { \new ChoirStaff ... } with:

\score {
  \new ChoirStaff
  <<
    \new Staff
      %% include "Volta_engraver" for the topmost Staff only
      \with { \consists "Volta_engraver" }
      { \new Voice { \global \first } }
    \new Staff { \new Voice { \global \second } }
  >>

  \layout {
    \context {
      \Score
        \remove "Timing_translator"
        \remove "Default_bar_line_engraver"
        \remove "Repeat_acknowledge_engraver"
        \remove "Volta_engraver"
    }
    \context {
      \Staff
        \consists "Timing_translator"
        \consists "Default_bar_line_engraver"
        \consists "Repeat_acknowledge_engraver"
        %% include "Volta_engraver" for all Staffs
        %\consists "Volta_engraver"
    }
  }%end of \layout
}%end of \score
