Two Dimensional Filter Statistics ERROR

Hi Guys,

We've found an error in TwoDimensionalFilterStatistic Portlet. It duplicates columns and does not show columns for unsigned values (it shoulds). In the example I attach, you can see the same filter applied to two portlets "Filter Statistics" (which works fine), and "Two Dimensional Filter Statistics" (which doesn't). You can see that the resolution is duplicated and the asignee too, and does not appear colums and rows for unassigned issues and unassigned resolutions.

If you look at the total, you can see that the result is incorrect.

I've been looking for this bug in order to not duplicate it, but a couldn't find it.

Regards,

Andrés.
