Steps to reproduce:

1. Create a new project
2. Open a search window
3. Enter any query that returns results (p: dir="Assets")
4. Switch to Table view
5. Observe that Description entries are listed as expected
6. Right-click on the Description column name
7. From the Column Format menu, select any unsupported format (For instance - Material Property)
8. Descriptions disappear as expected due to an invalid format being set
9. Right-click on the Description column name again
10. Select the Default option

Actual results: Description column format remains invalid

Expected results: Description column format is reset to the default value
