Cant revert back to hierarchical report after clicking on flatten report

[Yonatan_Ido]

Hey,
In eCommerce —> sales → campaigns
I clicked on flatten report

I got this
The DataTable cannot be manipulated: Metadata for report Referrers.getCampaigns could not be found. You can define the metadata in a hook, see example at: http://developer.piwik.org/api-reference/events#apigetreportmetadata

my problem is that I can not revert back to hierarchical reports

My piwik has many ecommerce sites i manage with a lot of data
How can I revert back to hierarchical?

Thanks
