Hi @spespan,
It seems it to be the system’s font issue. Have you tried it with other system (without helvetica bold font installed). The theme uses these fonts(“Helvetica Neue”,Helvetica,Arial,sans-serif) in sequence. If one is not found it will fall back to next and if none of the fonts found, it falls back to sans-serif. In your system as you’ve installed Helvetica bold, the theme will use Helvetica bold font by default. If you check other sites with Helvetica font it will display the same font(bold). Either you have install Helvetica regular font or remove Helvetica bold font, and the default font falls back to Arial.
Regards,
Mahesh
