Report is deleted when I cancel a modification

-- HikaShop version -- : 2.3.0
-- Joomla version -- : 2.5.18
-- PHP version -- : 5.3.28

When I modify a report which displays a table or just open it for any reason the report is deleted when I click on Cancel when I want to discard all modifiations.

I can't reproduce this issue.
Do you have the same problem on a fresh install?
Just to make sure: You simply edit a report and click cancel and the report is deleted?
What's your browser? Do you have the same issue with a fresh new report?
