Changing Workflow Scheme changed the "Add" date of all issues, can I restore the originals?

Question

I changed the Workflow Scheme of my project. When I did that, it basically added every issue to the new workflow. This result is that all of my reports are useless. The Sprint Burndown and Version Reports all think that every issue was added mid-sprint.

Thanks for the reply!

It does appear as if the "Updated Date" was set at the time of changing the workflow. When I look at a burndown chart, for example, I'm thinking the reason it's whacky is that every story has this as the "Event Detail":

Open issue moved into board (from an unmapped status)

So Jira thinks all every story was added at that moment.

I wonder whether all your new statuses are mapped into the columns for the agile report?
