To reproduce:
- Open attached project and launch "scene"
- Hit Play and select the Main Camera
- In Inspector, toggle the "label" parameter under 'HDR'
- Observe that only "One" and "Two" are displayed and that user can only select 'One'. In the 'popupBug' script, the string says "var popupItems = new string[] {"One","One","Two"};"

Expected result: If the string says {"One","One","Two"}, I would expect the drop down to reflect this.
