Ah… Actually, I guess what might be going on. Are you using
a version of LilyPond that uses Guile 2? Homebrew, for
example? What does #(display (version)) print?

LilyPond has a bug in Guile 2 where the nesting of generated
bookmarks is incorrect. See

https://gitlab.com/lilypond/lilypond/-/issues/6302

It's possible to work around it by editing the file
ly/toc-init.ly in the LilyPond installation to change the
line

   (children . ())

into

   (cons 'children '())

Best,
