Could you please provide the original, working (with an older LilyPond 
version) state of your code before convert-ly changed it? The code is a 
bit opaque and doesn't seem to be written very robustly (what with the 
hardcoded nested 'element / 'elements selection); it would be easier to 
start from a working version of the code.
