Scrolling through the ListView inadvertently displays duplicate elements

When a ComboBox is set as elements in a ListView, it can see that the option is set to the wrong element when selecting the ComboBox. 

1. Open the attached sample project
2. Right click on EUW_ListView.uasset with ListView in the editor and execute “Run Editor Utility Widget”
3. Select an element and choose one from the combo box

Result:
Scrolling will show duplicates of the previously selected element

Expected:

Elements do not appear in duplicate
