Issue in Grouping Table

[Pavan]

  As we can't share our original data we have given sample data.
We are facing some issue here.
Some of the rows are not displaying when grouped in table.
For example

My Data
------------------------
IdTest IdTestName IdGroup(Datatype : String)
1         test1         1
2         test1         1
3         test2         2
4         test2        2
5         test3        3
6         test3        3

When i have grouped the table using IdGroup

Output is displayed as
--------
 test1
 test2

Expected Output
-------------------------
test1
test2
test3


Some of the data is  missing in this ouput.Any reasons or cases why these rows are missing?

Hi Pavan,

We have not been able to reproduce such a problem in our local tests and would appreciate if you provide us with a runnable report using sample data that exhibits the issue. Once we review it, we would be able to provide you with more information.
