    Probably what is happening is that the page size for the subreport needs to be increased.

    In the main report, your subreport height is set here: height="92". That serves to set the minimum height of the rendered subreport. Making that larger or smaller will neither help nor hurt your issue. But if your page size is smaller in the subreport than it is in the main report, that would explain the behavior that you are describing.
