Instrument change – rests are missing within the bar.

I am writing an orchestral score. I have 3 percussionists. When there is instrument change, the rests are missing within the bar.
See the attached example and the difference between contrabassi parts and percussion. What can I do to restore the rests? I have a lot of this kind of situations in my score.

Unfortunately this is a known limitation of instrument changes at the moment. There’s no good solution to this problem, but you should find that adding a note in another voice at the end of the bar and setting it to be stemless and transparent (by way of the ‘Color’ property in the General group of Properties) forces the instrument change to happen later, and hence will cause the remainder of the rests to appear.

Thank you for this solution, Daniel.
