Power Pivot :: DAX Function ALLSELECTED Doesn't Refresh When Using A Date Hierarchy For Rows

I've encountered an issue where the ALLSELECTED function works fine unless I use a date hierarchy, i.e. year, quarter, month, date, for the rows in a pivot and then use a year slicer, select one or more years individually, and the clear the filter on the slicer.  The year(s) that I selected in the slicer remain at 100% in the pivot instead of returning to the subtotals for the unfiltered slicer.

This only occurs when I use a calendar hierarchy for rows and a date field for the slicer, either from the hierarchy or a regular date field.Below are images of the normal behavior and then the result after following the steps above. Can't figure out why the calendar hierarchy is causing the issue since it works for all other time functions, etc., and follows best practices such as contiguous dates, etc.
