Waitlist's Last X Days filter is incorrectly excluding items that should qualify to appear within the search. For example:  If we search a specific SKU (8113NP), without a filter, it appears.  The first and last post dates are both from this week.  If we add a filter of "Last 30 days" or "Last 60 days", it disappears.  If I filter by "Last 90 days" it appears.
