Rekordbox 2.0.1 doesn't hold given BPM (mountain Lion)

When i'm on my macbook with lion on it, everything works fine.

When i'm working on my Imac with Mountain lion on it, the track i'm clicking on to see in the player of rekordbox

looses his grid and theres now bpm.. when I quantize and give him the correct bpm the track looses everything

when clicking on a other song...
