Have you tried refreshing your fontconfig cache (i.e. the system cache in /var/cache/fontconfig)? I encountered similar issues a while ago with System Monitor and Tweaks (and so did others, who also reported the bug), and it seemed to be caused by a stale cache. IIRC you don't need to install Cantarell as user, but you may still do so if you wish.
