I am afraid that your problem description is not every clear and the screenshots don't help very much.
Are you expecting to see the selected value against a field name in a multibox after making selections? If you select a single value (or only one value is possible due to other selections), the value would normally display in the multibox. If more than one value is selected, then only a beacon (highlight) is displayed.

The multibox titled "Overall status" in capture1 shows the value against all fields when multiple selections are made. But in capture2 the same multibox is showing only a beacon against all fields when multiple fields are selected.
I wanted to know that if there are any properties that'll enable me to show value against all fields when multiple fields are selected?
