Spanning issue with group left option when subtotals are added

We use Oracle 11.1.1.7.0 version to develop reports.

Below are the requirements of the report.

1. Should display subtotals for groupings using group left option. Ex:

      There are 2 groupings:group by NAME AND then group by CLASS .both should display its subtotals.

2. The Group header should display in all the pages.

Work around done:

For point 1-Inserted data through table wizard using Group Left option and it displays the required contents.

But when we add the rows manually to include Subtotals we get issues with Spanning i.e. the alignment gets disturbed.

For point 2-When we use the syntax
<?attribute@block:xdofo:rowspancell-repeat-nextpage;'true'?> in the column that has to be repeated, the header repeats in all the pages.
