I am building a report that breaks down overdue actions for my company's task management software.
I have created a row group that allows users to toggle visibility of different action codes to drill down into specific tasks, however, when the report is run, there is a blank row between each of the grouped fields.
Here is what the report looks like within 'Design' mode in Visual Studio:

The bottom two rows are the ones that are to be hidden under the 'Expr' row:

However, when I run the report, it appears with a blank row in between each toggle row:

This blank row seems to disappear once the row group is toggled open. How can I get rid of this blank row?
Thanks in advance for any help you can provide!
