I have a fairly simple workflow that finds documents in a folder and then emails those documents in their native format in a zip file. The workflow was working fine until today when we added an additional email address in the To field of the email. After that it started sending the zip file, but with .lfe files inside of it. I also tried not zipping the files, but it does the same thing. The Edit Attachment's windows is setup as follows:

No matter what I seem to do it keeps sending them as .lfe files. Any ideas on how to fix this or why it might be happening?
