Has anyone ever seen this before, nmap is showing port 21 to be open on a machine on the internet, but 21 is not listening on that machine. It happens to all machines I scan outside the local area network.

What scan type are you using. Try using the --packet_trace flag to see why nmap thinks port 21 is open?
