Re; Volta problem

[Jay Hamilton]

I'm resetting a cello part for a student everything works except the 
last 3 measures.
The 1st ending should be after the tied g2. ~ g and it's not.  What have 
I got wrong?  I've always hated this 'volta' thing I wish one could just 
somehow put these endings in with \markup because I'm not interested in 
the midi for it.
here's a snippet that shows the problem
Thanks

\version "2.18.2"
\header {
  title = "Overture- Lully"
               }
#(ly:set-option 'delete-intermediate-files #t)
#(set-default-paper-size "letter" )
 #(set-global-staff-size 18)

  \paper
 {
 indent = 30
 short-indent = 15
 right-margin = 30
 top-margin = 15
 bottom-margin = 15
 }
voice = \relative c{
\key f \major
  \time 4/4  \tempo "Gravement"
\override Staff.TimeSignature #' style = #' ()
\override Score.BarNumber #'break-visibility = #end-of-line-invisible
\set Score.markFormatter = #format-mark-box-numbers
\clef bass
\set Score.skipBars = ##t
\time 3/4
 \repeat volta 2 {
\mark #80
d4 d\downbow a c d8 (c bes a)
bes4.->\downbow a8\upbow g4->\downbow
c, d2->\downbow |}
\alternative { g2. ~ g2.}\breathe {g2.\fermata}
 \bar "|."
}

\score {
    \new Staff = voice \voice

  \layout {\context {
\Score
\remove "Bar_number_engraver"
} }
  \midi { }
}
