WW Food and Point Issues - WW Broc and cheddar baked potato

I just got a Weight Watchers Broccoli and Cheddar Baked Potato dinner. The box said it is 4 points but when I figured it on on my WW. calculater, it came out to 5 points.
Calories 260

The box said 4 points per serving and the package is one serving size.:?: Any ideas??? Wendy

The information on the box might have been calculated using the old points formula - before the 4 point fiber cap.

When buying WW Smartones you can tell if they are from the old system by looking at the front of the box. If it says 123 success in the bottem corner you know you need to recalculate the points. :)
