This is the issue described in the end of the grace note section here http://lilypond.org/doc/v2.20/Documentation/notation/special-rhythmic-concerns#grace-notes .
If you insert a spacer of the same length ( \grace s16 ) in all other staves at
the same time (after "\repeat \volta 2 {" ) the doubled repeat bars will
disappear.
