.processed appended to file and automated upload

Winscp version 5.7.6 (build 5874)

Windows Server 2008r2

When using automation through scripting to upload a file, I get .processed appended to the end of the file name after upload. Is there a way to stop this from happening as it is interfering with the automated processing of the file by the other party. Is this something that can be turned off or is this something that is not coming from WinSCP? When I manually drag and drop, I do not get the .processed appended.

Script:
#connect to sftp site using a password
open sftp://User:password@65.99.xxx.xxx/ -hostkey="ssh-rsa 3072 bc:17:08:be:81:ba:7a:f7:c8:cb:d9:74:cf:84:30:32"
#upload file
put -delete D:\PatientTrak\*.* /
#exit
close

Batch file command: C:\Program Files (x86)\WinSCP>winscp.com /script=patienttrak.txt

Command Prompt Output:

C:\Program Files (x86)\WinSCP>winscp.com /script=patienttrak.txt

Thanks

WinSCP does not do that. It must be the server.
