Dal Segno - Sign missing

This post is a few years old, and according to Anthony Hughes video we can now add Segno signs, etc to our document. However, when I try to add a Segno, or Coda sign under the Repeat Sections menu, all I’m getting are little boxes. I’m using Dorico 5 Pro and I’m sure this is a glitch. Any suggestions on how to fix this? Thank you

ahh, ok, I’ve solved this. I needed to change the font under character styles > music text to Bravura.
