Cause\Possible Cause(s)

Using "Object instance" when choosing a source for sub report, is a legacy approach. It would create an instance of each sub report in the main report's list of elements (which is not best practice for multiple subreports approach).

Solution

Our recommendation is to use the "Type name" option for .NET type report definitions (.CS or .VB files).
