Pierre-Luc, try running your code with default layout options. I've written
and ran (with 2.24.4 and 2.25.25) the two first systems of your score and
it seems ok.

%%Code starts
\version "2.25.25"
melody = {\new Staff { \new Voice \with {\consists "Ambitus_engraver"} {
\clef bass

"Intro" }
\textMark \markup \bold "rubato"
\compressMMRests R1*2

"1 COUPLET" }
\tempo "a tempo" 4 = 64

a,4 r8 a,8 g,4 c
f,4 r8 f,8 e,4 e \break

"2 COUPLET" }

harmony = {\new ChordNames {\chordmode{
\compressMMRests R1*2
c2 e:7

f2:7+ c/e

c2 e:7
a:m c4/g c:7
f2:7+ c4/e a:m7
}}}
\score {<< \harmony \melody >>}
