AIX 5.1 missing first letter

I have a the same problem with AIX 5.1
The folders on my AIX 5.1 is missing the first letter.
For exampel "/usr" is shown as "/sr" , /tmp is show /mp , and not possible to klick.
I've tried all list options but no success.
Servers with AIX 4.3, Tru64 are OK.
I have the last version of SmartFTP.
I tested other ftp (Ws-ftp, FileZilla) and I do not have the problem.

Hello ...

Can you send a raw directory listing of the directory?
Right-click on the directory/folder in the treeview and then select "Show Raw Listing" from the context menu.

Please send the system information from the menu: Help->About and a log of your FTP session as well.

Thank you.
