Problems with Filesonic FTP – Same File Uploads Multiple Times

Is anyone else having major problems uploading to Filesonic using FTP? Maybe I just have my settings wrong, or maybe it’s something else, but it seems like anytime I try to upload a batch of files to Filesonic using FTP, multiple files will keep getting uploaded over and over and over again.
For example, I am uploading the following files to Filesonic using FTP:
File name: 001
File name: 002
File name: 003
File name: 004
File name: 005
File name: 006
Files 001, 002 and 006 will upload just fine, but files 003, 004, and 005 are uploaded again and again, over and over! So my end result looks something like this:
File name: 001 has been uploaded once
File name: 002 has been uploaded once
File name: 003 has been uploaded 6 times
File name: 004 has been uploaded 3 times
File name: 005 has been uploaded 9 times
File name: 006 has been uploaded once
What the fuck is going on […]
