When the IN operator is used in breadcrumbs, expanding the filter and running again removes the values from the IN condition, and therefore produces no results. The IN operator can be generated when drilling down into a report using a "Select Multiple Input" Interactive Filter.

1. Create a Single Score report against the [incident] table, with no conditions.
2. Open any PA dashboard (Performance Analytics > Dashboards), such as "Incident Management".
3. Add the OOB "Incident Assignment Group - Multiple" Interactive Filter to the tab:
   __a) Click the "Add Widgets" icon (the '+' sign)
   __b) Choose "Interactive Filters" from the drop-down
   __c) Click "Reference"
   __d) Select "Incident Assignment Group - Multiple"
   __e) Click "Add"
4. Add your report to the Dashboard:
   __a) Click the "Add Widgets" icon (the '+' sign)
   __b) Choose "Reports" from the drop-down
   __c) Select your report, and click "Add"
5. Hover over the title bar of your report, and click the cogwheel. Check "Follow interactive filter", and click "Done".
6. On the Dashboard, click the Interactive Filter drop-down, and enter "Service Desk" (OOB, there will be multiple incidents assigned to this group).
7. The number will change on the report.
8. Click on the number to drill-down to a list.
9. Observe the breadcrumbs: Assignment Group IN (Service Desk), and the results.
10. Expand the filter, and click "Run".
    
    > Expected behavior: The Filter should work and returned the expected number of records based on the IN operator
    
    > Actual behavior: The filter now reads Assignment Group IN (), and no results are shown.
