Datatable Version #: 3.3.2 not updating output edited rows

I thought this would be relatively simple, everything I've set up so far works great, except when I'm trying to update the records at the end of the flow. I assign the Output Edited Rows from the Advanced section to a collection variable, then using a update record element I use that same collection as the records to update. But no update is made the debug log says that my variable is empty. 

Can anyone help me? @Eric Smith
