Hi Kim,
Would you mind to share your QWP version and SharePoint version? If you could attach your list with data (if possible) as a list template that would help too.
Meantime here you are a few tips about sorting:
– ezEdit->Display->Sort fields option allows you to sort the list when the page is displayed (predefined sorting)
– ezEdit->Display->Disable Multi Column Sorting allows you to enable/disable multi column sorting
Thanks,
