Here is a strange one, I imported a wf which was a duplicate file name. I knew that it was going to append a (2) to the end of the file name but that allowed me to copy & paste from the new to the old wf. After the wf information was copied I deleted the imported wf out of the vsult. The reseller told me I can delete them, but when I asked what the effect would be they did not know. REALLY! Delete them even though we do not what effect it will have on your vault.
