retrying a transfer that completed successfully

Hello: I have smartFTP pro installed on a win 2003 server. It works correctly most of the time however I have noticed in the transfer queue that it is retrying to send files that it has already successfully transfered. The log file states "Source file not found" which would be correct because it was removed after successful transfer. What causes the retry after successful transfer and how do you prevent this?

Please post the log of the transfer. To get the log double click the file in the transfer queue.
