HD TITLES CIRC REPORT

In the HD - Circulation report, the fields to enter a date range are grayed out.  Several reports allow you to switch between those fields and the time period.  Can this reported be fixed so custom date ranges be made (I was just asked for the top titles that went out in individual months).  While the circulation field is a way of getting the numbers, it doesn't give me all the information I need, so this report would be a much better option.

Thanks Katy
