Perhaps you are missing a font. When I compile your document, I see these fonts:

(Sorry, Retina screen, I can make smaller later)

In your attached PDF, I see:

Can you please post your .log file, as attachment?

Thank you very much for your time and your interest.
I uninstall MikTeX and after reinstall it. The problem disappears (!).
