Percussion rest problem

I have a percussion part with two instruments (Crash Cym. and Tambourine). They are set up as crash cym. stem up voice 1 and tamb. stem down voice two. I have notation opt set to pad rests in percussion voices and show rests also. I cannot get a rest to show in measure 1 for the Tambourine although it does work in measure 5. This makes me think that it’s not working because it is measure 1, is this correct?

Please see screenshot.

By the way, I flipped the stem on the crash cymbal part so that’s why it is pointing up.

This seems to work for me in a trivial example. Could you attach a small project that shows the problem?
