Chord symbols ot showing sharp or flat signs

I just upgraded to Dorico 4, and so far, it’s great - I really love the Capo functionality. But, I’m not seeing any sharp or flat signs in my chord symbols. They are there when I double-click the symbol to edit it, but they don’t appear on the page. I’ve confirmed that the Bravura and Bravura Text fonts are available on my system, and the signs display properly on the staff. Any ideas where I should look next?

Please reboot your computer, and you should find that everything then looks OK.

The one thing I hadn’t tried, it worked like a charm. Thanks!
