grace notes problem with unfold and volta

[Deborah Lowrey]

Dear Lilypond,

Sorry, it's me again. Anitra's Dance is proving to be
a challenge. The last fix worked for everything that
had only on grace note in the staff. So all the parts
are working except the 1st violins. (LOL, being a
violin player, I've heard that before) :-) 

When I use \repeat unfold I get the error:

The repeat of the first grace note gives an
incompatible stem error, but processes and the PS
shows the first regular note changed to a 16th, with
the two grace notes stacked in top.

If all I change is the unfold to volta, I get the
error:

I'm attached the first violin part so you can see
maybe what's going on.

Thanks for your help,

Deborah
