BB Calendar Conflict (Outlook)

I recently updated my 9700 to the latest OS and I noticed that this caused a problem with my calendar.

Inserted into the (Outlook) calendar I also have the Hebrew (lunar based) calendar dates inserted as all day, free time events. In the last OS this did not cause any conflicts, but with the new OS, when I sync the BB this causes every single calendar entry to come up as being in conflict (red, with X's next to the entry). (On the PC, there are no conflicts displayed).

Is there any way to fix this?
