The problem comes from "\unfoldRepeats" !
See the attached files for a stripped-down but complete example
of the construct; the desired print output is achieved using
"\cadenzaOn" and "\cadenzaOff", as suggested.

(1)
First, is this in effect the most straightforward way to obtain
the expected result?
What would the equivalent incantation using "Timing.measurePosition"?

(2)
In the 3rd attached file, when "\unfoldRepeats" is put back in,
warnings show up:
