Vista - Colors not shown on holidays in the Calendar Beta

Hello,
When login to my windows live hotmail mail account I go to the calendar
option on the lower left had corner and click on the calendar. Next it
brings me to the standard or beta calendar. When choosing the beta I
have already imported my holidays into the calendar and it seems to
work. The problem is that my windows xphome does not show and colors for
the holiday it just show 1 more ... but once I click on this link it
shows the holiday in colors. I know that this is still a beta version
but why does all other windows os show the colors highlighted and even
events and xphome does not. Is this a bug or is there a setting I don't
have correct.
