Tech Availability Chart "Unavailable" color not showing.

Since upgrading to the most recent version ( 8.0.0 Build 8006) we can no longer see the pink-ish color for "Technician Unavailable" on the Tech Availability Chart.
 
The leave times are still marked, but the color does not show up in the main view.
 
Any suggestions?
