C# session.GetFiles "remove" parameter not working?

This may be a problem on the server end rather than with WinSCP (as detailed below) but I'd like to stop here.

OS: Windows Server 2008
WinSCP: v2.0.50727
App Coded in VS2012, 32 bit

Summary: I have to pick up a file via SFTP that is placed there every 30 minutes. I would like to leave the copy there rather than remove it. No matter which way I set the flag on session.GetFiles it deletes.

Oddness: If I use the same code to pick up a copy of the file _that I placed there_ the copy deletes or does not delete appropriately <= makes me think the rights on the files are different, but they appear to be the same in both the log files and the WinSCP application.

Code used:

TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Ascii;

session.GetFiles(remotePath, localPath, false, transferOptions).Check();

I think there is something about the file I am copying. When I use WinSCP 5.1.5 build 3261 and drag and drop, the server generated file is deleted when I take from remote to local, when I drag a copy of the fin=le that I brought under a different name into the directory it is not deleted.

It looks like there's some process on the server-side that removes the file once it is downloaded.
Please attach a full log file showing the problem (using the latest version of WinSCP). Use drag&drop for the download test, not .NET code.
