The clear filters button allows you to reset your filters to their default settings. When you click on this button, any changes you have made to the filters will be undone, and the filters will be set back to their original state.

By default, the filters are set to show only in-flight cases. However, if you want to change this and view different types of cases, you can click on the 'More' button. This will expand the filter options, and you can select the filters that you prefer.
