Metronome marks not displaying/printing??

Whenever I input a metronome mark into any project in Dorico Pro 3.0.10.1051 (Oct 7), the beat value always appears to be missing (see photo). Anyone else having the same issue? Is there a fix?

Looks like a font problem.
Does rebooting the computer fix it?
If not, which font is selected for the metronome mark music font style in Engrave > Font Styles?

Restarting seems to have worked!
