Big issue! Big problem. Photolab 2 sends files to trash!

Big issue! Big problem.
After another crash using virtual copies and before exporting, my RAW file disappear from Photolab 2 and also from the original place in my HDD.
I then found it inside the Mac trash can with the .dop file.
Why is that? I do not know but it is a serious and dangerous issue.
I will now check all my files from the last days of editing to make sure I did not delete files without notice.
This is really annoying!
Dxo; please address this issue!

P.s.: this started on another topic but I found this behaviour so serious that I open a new topic.
