AutoRename not working on Remote site for Downloads

[Vic]

CoreFTP Lite v2.1 Build 1621
Using FTP
Binary transfer of .txt file
Remote box is Unix
Local box is Windows

When using Auto Rename settings for Upload and download (both checked Black) the rename of file moves from local to remote works on the remote FTP site (files are renamed on the remote site).

But when downloading from the remote site the file names do not rename on the remote site. However, I can rename them on the local site after a download. But that is not what I want.

These are the setting for the rename for the autorename for the upload and download: .txt -> .txt_%m%d%y_%H%M%S

Why can't I rename the files on the remote site after downloading from it?

Also I tried using Script/CMDS commands for Post Transfer downloading from the remote site.
I used the following:
RNFR %1
RNTO %1_%m%d%y_%H%M%S

I got vrn1.txt_%m%d%y_%H%M%S for the remote file when I was looking for the numeric mmddyy_hhmmss.

How can I make either of these methods work?

Note: When connecting to the remote site and folder it takes approximately 25 seconds to load it because of the amount of files. Could the rename be timing out on the download and rename of files from the remote site.

Did the rename of the file on the Download occur for the remote file? This is where I am having the problem.

The file downloaded to my box renames, but I want the remote file renamed after it has been downloaded to my box.
