Errors getting the totals in pivot tables (and event reports) with six-monthly periods

Hi guys,

These screen captures were taking from the Sierra Leone demo.

These are the totals of ANC 1st visit disaggregated per month: 132609

And this is the total from January to June 2014: 124771

The same problem is happening with event reports.

Could you please take a look at it? Thanks!

Regards

Jose
