Group totals overwrite if there is two groups

[tarakgandhi]

I have added two groups in the report and after adding 2nd group the group totals get overwrite, it seems all data prints in one line only. I have disabled the detailed band as I just want to print group 1 header, group 2 footer and group 1 footer. See the attached report output

The actual output is properly displayed in ireport, check below screenshot.

Even the grouping is not done properly. If I add detail band and group 1 band then the grouping works fine.
