SQL query returns 2 records in SQL Query but ReportViewer only displays the last record?

SQL query returns 2 records in SQL Query but report only displays the last record?

The following returns 2 records, but report only displays last?

SELECT * FROM [Case] Where (CaseItem IN (4,5)) ORDER BY CaseItem

CaseItem is an Integer

Seems like reportviewer does not execute simple SQL correctly.
