Fret Diagrams

[Peter Gentry]

This may be trivial but searches of themanuals etc have not born fruit.

How do you prevent the markup N.C. appearing where there is a note rest. In 
fact  N.C. does not always appear sometimes once in a
bar sometimes twice for no immediately apparent reason.

If r1 is replaced by R1 then no "N.C." markup.

I have been trying out  http://do.remifa.so/archives/sheet_music/  no N.C. 
markup with \version "2.12.2" but with 2.19.25  "N.C."
appears where the chordname would be if there was a chord


I have included a small(ish) sample I have not used R1 in this but if you do 
then no "N.C."

\version "2.19.25"



\include "predefined-ukulele-fretboards.ly"

\storePredefinedDiagram #default-fret-table \chordmode {c:dim7}
