I think what you want is something like this:

%%%%
\version "2.19.82"
<< \new ChordNames \chordmode { d1*2:m/a | e1*2:7/gis }
   \new Staff { \clef bass
     d4 \chordmode { d:m/a } f, q | d4 q f, q |
     e,4 \chordmode { e:7^5/gis } gis, q | e,4 q gis, q } >>
%%%%

ChordNames does not do magic with the notes provided.  You cannot just 
duplicate notes intended for a staff and get useful results.  Instead, 
use that context specifically when you want a chord to appear.  In 
addition to specifying durations for the chord changes, use \skip (or s) 
as needed when there is no associated chord.
