acciaccatura after repeat volta

[Jacques Verhagen]

Hoi,

A have  a problem with a  acciaccatura after a repeat volta.

Ik get two repeat signs. How can I solve this problem.

    \version "2.20.0"
      
      
      global = {
        \time 4/4
        \key c \major
        \tempo 4=100
      }
      
      
      
      melody = \relative c'' {
        \global
        \repeat volta 2 {
        c4 d e f
        g d g f
        e c d e
        f g a f
        g g b d 
        c,1}
        \repeat volta 2 {
        \acciaccatura{b16 c16}c4 c c e
        g f e d | } 
        \alternative {
        {c c e d
        b b b d8 f8 }
        {c4 c b g 
         c1 }
        }   
      }
      
      bassen = \relative c' {
      \global
      \repeat volta 2 { 
       c1
       g
       c
      f
      g
      c |
      }  
      \repeat volta 2 {
      c1
      g | }
      \alternative {
      {
       c
       g
      }
      {
      c2 g:7
      c1
      }
      }
      }
      
      
      \score {
        <<
      
          \new Staff { \melody }
          \new Staff{\bassen}
         
        >>
        \layout { }
      
      }
