Hi,
I tried with the same settings and the files were well sent on my side.
Can you try to send only one file with 'Scp Local File' parameter instead of 'Scp Local Dir' and 'Scp File Includes' to see if it works?
Another test you can do is to try without 'Scp Use SFTP' if possible.
Also, if you have access to the server you are sending files to, you could look at the log files of the SSH Server to see if there is any error, problem, or trace of the operation that could help to investigate on this problem.
