Date Picker

Hi I am using the datepicker plugin for a custom field.

When a date is selected, it is shown as follows: %21-%04-%2014

How do I prevent the % from being shown?

-- HikaShop version -- : 2.3.0
-- Joomla version -- : 3.2.3
-- PHP version -- : 5.3.28
-- Browser(s) name and version -- : Chrome, Firefox

Just worked it out... the format had defaulted them in.. very strange.
