Livecycle designer dropdown with multiple EditValues but the same RawValue issue

Hi

Very new but learning....

I am populating a dropdown with the following values

this.addItem ("Editvalue1", "Raw1");

this.addItem ("Editvalue2", "Raw2");

this.addItem ("EditValue3", "Raw2");

When I open the dropdown, i see the 3 EditValues.

If I select EditValue3, the dropdown shows me EditValue2 (I assume because they have the same Raw value)?

How do I resolve this?  Do I just populate with the EditValues and have to write code to define the Raw values based on the editvalue?
