I have several reports that need to be sorted in Descending Date order. 

My Report has Sorting configured based on Added Time but yet the report mind as well be in random order. It does not show up in the order that it should be. 

Yes i do also have grouping configured. 

Here is a picture of what i get.

march should be at top not Feburary. Notice march is mixed in.  There are lots of records so its hard to show here. This happens consistently accross all months and days worth of data.
