Unable to Change the Date Footer Filter in a Customer Saved Search

Consider the following scenario:

o    In the Criteria tab > Standard subtab, add Date is not empty
o    In the Available Filters tab, add the same Date field and mark Show in Filter Region.
o    In the results page of the saved search, the Date footer filter is disabled

The Date footer filter is disabled because of the criteria set. Instead of using Date is not empty, specify a Date or remove the Date field in the Criteria tab > Standard subtab.

Note: The above scenario is applicable to all type of saved searches.
