Your Bravura font is almost ok (it appears a little too bold to my taste though).
Your Petaluma font appears as Classical.
Sorry I cannot help you with that, we’d need help from a Mac user.
Regarding the tremolo symbols for Bravura and Petaluma fonts, I also noticed that they are incorrectly placed. they should be centered on note stems. This one I will report.
I just tried resetting the font cache and Disk First Aid is not reporting any problems.
But the problem is not solved.
The strange thing is that other software, including Dorico, find the fonts and load them correctly.
Cubase loads wrong fonts (Bravura instead of Petaluma, Calssical, etc.) and they are incomplete.
