Cubase 8.5 & Score Fonts

Hi,
I am running Cubase 8.5 on the latest El Capitan and I find that some fonts display properly on the score and others do not, i.e., the font displays as some default. I never had this problem in Cubase 4 running on Windows (hate Windows anyway). In fact I am finding that most fonts do not work.
Does anyone know why certain fonts won’t work? Is there a way to make it happen with any font?
