Recuva not deleting files

Guys I recovered some sensitive data that was lost. But now I can still find it in recuva even when the file is not there in my laptop. I tried to securely overwrite it using recuva but it failed. Even Ccleaners diver wipe was not effective. Guys need some suggestions asap.

What's the file system? Normal or deep Recuva scan? What's the error message when you try a Recuva overwrite?
