I can hear notes only when clicking them

I thought I’d seen this problem solved before, but I can’t seem to find any posts to that effect.

On a couple of my staves, I can hear the instruments just fine when I click individual notes, but on playback, they’re silent. Very odd. In the Play tab, the dynamics and MIDI (CC1) information look just fine.

Please help, gurus.

Never mind, solved the problem by switching the notes to a new voice, then back to their original voice.

Looks like a bug in the software, but fortunately that got my playback back on track.
