I don't know if this is necessarily a problem. The notes are relative to the 
preceeding note. Since the note directly before is in the octave you want, 
entering g, puts the note yet another octave lower. The octavation is relative 
the directly precedent entered note, regardless of whether that note is typeset 
or not.
example:
\score {

%  \keepWithTag #'notate
  \keepWithTag #'midi

  \relative c' {
     \clef bass
     bf8 a16 g   a8 d,   g ef c d
     \tag #'notate {g,1 \fermata} 
     \tag #'midi {g,1.}
  }

\layout { }
\midi { }

}
