Unexpected column title in the Risks grid

Issue Summary

The title for a column in the Risk grid appears twice when a custom field (of type Custom Dropdown/Select List) is used.

Steps to Reproduce

First, create a custom field (Custom Dropdown/Select List type) by following these steps:

1. select the Settings gear Gear in the top navigation bar if you're using the new navigation. If you're using the old navigation, select Administration in the left Nav menu.
2. On the left side of the page, select Details Panels Settings in the Settings section.
3. Select a portfolio from the Portfolio dropdown menu.
4. Select a work item type, Risk, from the Work Item dropdown menu for this case. The list of default and custom fields is displayed on the right side of the page.
5. Select the Add Custom Field button from the upper-right section of the page. The Customize Your Page Level Experience menu displays.
6. Select a field type, for this case, a Custom Dropdown, for the new field from the Custom Field Type dropdown menu.
7. Enter a name for the custom field in the Custom Field Label text box.
8. Select Create at the bottom of the menu to create the custom field.
9. Select Add Item to List to add another field value. An Option 2 text box will display. Repeat for as many field values as you need.
10. Select Save to save the list of values.
11. Set the new custom field as active on the Details Panels Settings page.
12. Go to the Risks grid and then add the newly created custom field as an Active column (More Actions > Column Shown)

Expected Results

Actual Results

The column title appears duplicated/twice.
