Views argument summary displays incorrect count of record entries & incorrect 1st item in the summary list in descending order

Continuing from an earlier issue: "Argument summary in Views is broken" (http://drupal.org/node/1027752)

View using the Date: Date (node) argument summary (Summary, sorted ascending), the 1st item in the summary list is in the incorrect order and displays the incorrect count of the record entries. The remaining date counts are correct and in the correct descending order.

The list above only shows the first 10 items per page. 'Sunday, February 13, 2011 (16)' should not show as the first item in the list in descending order. Further down the pager shows 'Sunday, February 13, 2011' is found again, in the correct order and with the correct count of (1)!
