Scheduled Event - encrypt and move deletes all files

I have a scheduled event and my goal is to pick up a file at the source, encrypt the file, move it to the target and delete the original source file.

My event steps are as follows
1 Find the file in the source virtual folder
2) Encrypt the file
3) Move the encrypted file to the target
4) Find the original file in the source folder
5) Delete the original source file

The event performs the first four steps well, but on the delete step it deletes not only the original file, but also the encrypted file on the target. The source filter on the delete step doesn’t seem to work at all.

Anyone else experiencing issues on a delete in a scheduled event?
