Hi Steve,
If you wish to display unique values on the report, here are a few workarounds:
1) Go to the Database Menu > Check 'Select Distinct Records' or
2) Insert a Group on the field that causes these duplicates > place all fields on the Group Header or Group Footer and suppress the details section
If there are multiple fields that form a unique record, then create a formula that concatenates these fields and then group off of this formula field:
{Field1} & {Field2} & {Field3}
