Tasklist Macro is broken

Steps to Reproduce

1. Created a new page
2. Insert a Tasklist Macro

   {tasklist:checklist}
   ||Completed||Priority||Locked||CreatedDate||CompletedDate||Assignee||Name||
   |F|M|F|1371784117215|          |admin|Sample1|
   |F|M|F|1371784127222|          |admin|Sample2|
   

3. Save the page

Expected Behaviour

• The Tasklist macro adds a list of tasks to the wiki page. Users viewing the page can modify the tasks without having to edit the page. After ticking the check box it should stay.

After ticking the check box, it will be untick after page refresh.

At some point it is also acting as unable to untick the box if they are already ticket
