jQuery Datepicker opens on future date

Hi, I'm trying to use the jQueryUI Datepicker with a US date format and I find that when I click on an existing date, the datepicker opens at some future date in 2021. When looking at the examples on your site, it would appear its also happening in your own examples: https://editor.datatables.net/examples/dates/jqueryui-formatting.html - select any row and edit it - check the date shown in the editor form. I'm seeing this in both IE10 and Chrome.
