Use of median in a report

[smtest]

hi,
i am trying to use median in my report. what is happening is, if use median in more than one column. It shows same values in both columns.
example:
       Col1   Col2
A       5      6
B       6      7
C       7      8
D       8      9
E       9      10
expected result is :

Median   7      8

But it is showing
Median   7      7

I noticed one more thing, if i switch columns i mean  Col2 first and then Col1
the result is
Median 8    8

pls advice
thanks
