Item Finder displays wrong Qty On Hand - Optional Field.

Hello all.

We believe we have found an issue with the Item Finder Qty on Hand field. When the user applies a filter using an Optional Field, the finder will display the wrong qty on hand.

For example, if we filter for "Item Number" starts with 20149 (Looking for items between 201490 and 201499), the finder will report the correct quantity on hand.

If we filter using Optional Field "Diameter OD Body" starts with 0762, the same qty on hand displays for all records.

Has anyone else experienced this issue?
