PowerView for Sharepoint 2013 , No Column Totals in Matrix Report

Hi,

I am using PowerView in sharepoint 2013 "SSRS Sharepoint mode, when I create  Matrix report I dont get column total, even though it is selected from matrix option.

I found this happens when I use in the matrix a field that is sorted by another column "in the PowerPivot model", 

But when when I build the exact same report in in PowerView for Excel 2013 I get the column totals normally

please check the image below which shows what i get from Sharepoint an what I get from Excel, the missing totals should be where i draw the rectangle 

Any Idea?

.
