Calendar problems

[cup2usa2010]

I just flashed BigJ's 1.1r rom, and now when i look at the month view in the calendar, the blue boxes and up and down triangles that indicate appointments do not appear. My appointments show everywhere else, day and week views as well as today screen, but they disappear after a day or so after flashing in the month view. I've reflashed a couple times thinking maybe something happened, but it happens again a day or two later. Anyone else have this problem or know how i can fix it? Any help would be great.
