No dots in chord diagram in second flow - bug?

When I add a second flow the chord diagrams don’t have dots anymore.
What am I doing wrong?
Or is it a bug?

Are you running the most recent version of Dorico, Albus? Make sure you’re running Dorico 3.1.10. When I open your project in the current version, the chord diagrams appear as expected in both flows.
