Oneimage delete does not remove file from disk

I was testing oneimage delete, it removes the file from the db but it does not delete the actual file on disk in the datastores:

 # ls -lah /var/lib/one/datastores/1/

As you can see there are more images than in the db, the new ones from april 13 were tests.
Seems like a bug? version 5.12
