Your code is far from minimal (and not working because guitarMusic isn’t 
defined and some curly braces are missing) but I was able to find your 
problem in this smaller (but also not minimal) example:

%%%%%%%% BEGIN EXAMPLE
\version "2.19.46"

mandoMusic = \relative c' {
  \new Staff = "mando"
  \time 6/8
  R2.
  \override NoteHead #'style = #'slash
  \repeat percent 6 {
    <<
      \chords \with {
        alignAboveContext = "mando"
      } { s4 c8 s4. }
      { r4\mp b'8 r4 b8 }
    >>
  }
}


\score {
  \new StaffGroup <<
    \new Staff {
      \mandoMusic
    }
  >>
}
%%%%%%%% END EXAMPLE

You define a (new) Staff which contains mandoMusic which contains a 
(new) Staff called “mando” which contains the \time 6/8 and nothing 
else. Inside of the (outer/upper) Staff a new ChordNames context is 
created that is aligned above the other (lower) Staff. So there’s just 
one unnecessary Staff.

Two possible solutions:
1. create only the outer staff, call it “mando”, and align the chords 
above this staff:

%%%%%%%% BEGIN FIRST SOLUTION
\version "2.19.46"

mandoMusic = \relative c' {
  \time 6/8
  R2.
  \override NoteHead #'style = #'slash
  \repeat percent 6 {
    <<
      \chords \with {
        alignAboveContext = "mando"
      } { s4 c8 s4. }
      { r4\mp b'8 r4 b8 }
    >>
  }
}

\score {
  \new StaffGroup <<
    \new Staff = "mando" \mandoMusic
  >>
}
%%%%%%%% END FIRST SOLUTION

2. separate ChordNames and Staff from each other; you won’t have any 
alignment issues:

%%%%%%%% BEGIN SECOND SOLUTION
\version "2.19.46"

mandoMusic = \relative c' {
  \time 6/8
  R2.
  \override NoteHead #'style = #'slash
  \repeat percent 6 {
    r4\mp b'8 r4 b8
  }
}

chordMusic = \chordmode {
  s2.
  s4 c8 s4.
}

\score {
  \new StaffGroup <<
    \new ChordNames \chordMusic
    \new Staff \mandoMusic
  >>
}
%%%%%%%% END SECOND SOLUTION
