Sorting a column with dates on the Page Property Report macro does not work correctly in some language settings

Issue Summary

The Page Property Report macro does not sort correctly columns that have dates, inserted in the listed pages using the Date macro, when Confluence is set to German or French languages.

Environment

• Have the browser set to German or French language
• Alternatively change the User settings in Confluence for either German or French language

Steps to Reproduce

1. Create 3 pages, each with the Page Properties macro, containing a table such as:

   Description	<enter some text>
   Date	<insert a date with the Date macro

    Enter different values for each page, namely different days and months for the dates.

2. Add the same label, for example "pageprop", to the 3 pages;
3. Create a new page and add the Page Property Report macro, specifying the label created in the previous steps;
4. Viewing the latest page, click on the Date column and check the order.

Expected Results

The list in the page is correctly sorted per date, either ascending or descending depending on the previous sorting order.

Actual Results

The list order is inconsistent.

Notes

This has been reproduced with German and French language but other languages may be affected as well.

Workaround

There is no known workaround other than selecting English as the language settings for the user.
