Repeat last bar sign is ignored within a repeat section.

Dear all,
in the attached example a "Repeat last bar" symbol used on a wood block , within a Repeat section, is failing to generate any sound when the repeat section is entered the second time and after the repeat section as well the sound is no longer generated.
I encountered this issue in my own score and then created the attached example in order to test it and to allow you to reproduce it.
Thankyou for your support.
