Rekordbox user interface incomplete

Hi,

On the Rekordbox user interface (Performance mode) several fields, such as time, track time, musical key and BPM (in the middle of the jog wheel) are not shown completely (apparently they are "too long" so they are truncated an an ellipsis (three dots) inserted. See screenshot.

What may be the reason?

System: MacBook Air Mid 2011, OS X 10.11.3, Rekordbox 4.1 (problem existed with 4.0.8 also) [View Preferences changes tested: Font Size Lange or Small, Line Space Large or Small, Artwork Large or Small does not resolve the situation]
