    Hi Kieren & Carl;
    
      Well, since you have already provided an MWE that shows it works as
    documented, may I provide my full Lilypond code?  It is only a halfway
    completed Piano arrangement of "The Elephant" from the ""Carnival of
    the Animals", by Saint-Saens. It is not long and it is simple.
    Perhaps I'm doing something really stupid...

In the original piece, when it says "L.R. sempre 8va bassa"  I believe it means 
all of the pitches need to be shifted down by an  octave.  But when you entered 
the pitches, you didn't lower them by an octave to the sounding pitch, you 
entered them at the staff position pitch.  Thus, when you lowered the staff by 
an octave with \ottava, the pitches shifted up by an octave on the staff.

TLDR; Your pitches are an octave too high.
