Chord on third beat appears on second beat.

Hi,
I am not sure I understand your question about the hidden notes. I use the slash notes on every beat which are hidden notes.
I also tried to include "blank chords" on the different beats (ie. a space instead of just going to the next beat for input..)
Here is the way I entered the chords :
Select beat 1 on measure 1(hidden note). Ctrl-k Cma space d-7 space E-7 space fma space g7 space a-7 space b-7b5 space c6 space .
In any cases, the chord on beat 3 or 4 are always put as if they followed directly beat 1.
The plugin gives
C^,D-7, , ,| instead of
C^, ,D-7, ,|
Have you had any success ??
I include the .mscz file and .xml
