When attempting to view either DLP Investigations - User Incident Details or DLP Investigations - User Incident Search reports the results of the report is always 'No Data'

The four parameters 'Email Address' , 'Machine Name', 'IP Address', & 'Username' are defined to be exact string matches. This causes the report to look for results where these four parameters have a blank value.

Updated the query statements that pull these four parameters values to return all results if the parameter field is empty.
