Birthdays in Calendar Widget

My friends' birthdays are already in my Google Calendar, so when the SGT's calendar automatically displays their birthdays from my contacts list, everybody's birthday appear twice.

I have turned this option off in the calendar, so everything looks OK in the calendar. Unfortunately, this hasn't changed the calendar widget, so everybody's birthdays still appear twice in the widget.

Hopefully I'm missing something obvious, but I can't see a setting for the calendar widget.

I know I can download another widget from the market place, but it seems a shame to do that when Samsung has already provided a widget.

 

I'd already tried that and it didn't work. I'll try deleting it, turning the Tab off and on, then adding it again.

Thanks.

 

Still didn't work after turning it off and on again.
