6.2 Advance search calendar malfunction

In 6.2, the calendar search seems to not be working correctly. If I do a single calendar search such as equals or more than, the calendar selector's arros don't work. To go to a previous month, I have to first select whatever day overlaps into the current months calendar then click on the calendar icon and select the date that I want in the previous month. If I try to do a "between" search, then the second calendar that appears will not select a date.
