There’s a spurious instrument name setting. But given the structure of your
code, it’s very hard to spot.
Might I suggest putting all of your note code into variables, then building
them together in the score later, so that the code is easier [for a human] to
parse? Something like:
%%% SNIPPET BEGINS
\version "2.19.80"
#(define-markup-command (stack layout props args) (markup-list?)
(interpret-markup layout props
#{ \markup \tiny \raise #0.5 \general-align #Y #CENTER
\override #'(baseline-skip . 2) \right-column #args #}))
sha = \markup { \fontsize #-3 \sharp }
natu = \markup { \fontsize #-3 \natural }
fla = \markup { \fontsize #-3 \flat }
theMelody = {
\clef "treble"
\key f \major
\time 4/2
\set Staff.instrumentName = #"Cantus"
\set Staff.timeSignatureFraction = 2/2
d''1 d''2 cis''2 | %P1V1-1
d''1 f''1 | %P1V1-2
cis''2 d''2 e''1 | %P1V1-3
d''2 \rest e''2 e''2 d''2 | %P1V1-4
}
theLyrics = \lyricmode {
\set associatedVoice = "melody"
TO1 heare2 me,2 Lord,1 be1 thou2 in-2 cline'd;1 2
My2 thoughts2 O2
}
theBass = {
\clef "bass"
\key f \major
\time 4/2
\set Staff.timeSignatureFraction = 2/2
d1 d2 a2| %P4V1-1
bes1 f1| %P4V1-2
a2 d2 a,1 | %P4V1-3
g,2 \rest a,2 c2 d2 | %P4V1-4
}
figures_upper = \figuremode {
< Pretonal >2 < _ >2 < _ >2 < _ >2 | %BC-1
< 5 >2 < 6 >2 < 6 >2 < _ >2 | %BC-2
< _ >2 < _ >2 < \sha >2 < _ >2 | %BC-3
< _ >2 < 5 >2 < 5 >2 < 5 >2 | %BC-4
}
figures_lower = \figuremode {
< Tonal >2 < _ >2 < _ >2 < _ >2 %1
< 6 >2 < _ >2 < _ >2 < _ >2 %2
< _ >2 < _ >2 < _ >2 < _ >2 %3
< _ >2 < 5 >2 < 6 >2 < 6 >2 %4
}
\score {
\new StaffGroup
<<
\new Staff
<<
\new Voice = "melody" \theMelody
\new Lyrics \theLyrics
>>
\new Staff
\with {
instrumentName = "Bass"
\override VerticalAxisGroup.staff-staff-spacing.basic-distance = 5
}
\new Voice \theBass
\new FiguredBass
\with {
\override VerticalAxisGroup.nonstaff-unrelatedstaff-spacing =
#'((basic-distance . 0) (minimum-distance . 0) (padding . 0.5)
(stretchability . 10))
}
\figures_upper
\new RhythmicStaff s1*8
\new FiguredBass
\with {
\override VerticalAxisGroup.nonstaff-relatedstaff-spacing =
#'((basic-distance . 0) (minimum-distance . 0) (padding . 0.5)
(stretchability . 5))
}
\figures_lower
>>
\layout {
\context {
\RhythmicStaff
\omit TimeSignature
\omit BarLine
}
}
}
%%% SNIPPET ENDS
I’ve done a couple of other things to simplify the \score block — such as
tweaking the \RhythmicStaff context in the layout block rather than inline —
and there are more things you could (and I would!) do to take this philosophy
even further.

No doubt! I just don’t have time to look at that right now.
Hope this helps!
Kieren.
