Can't disable copying of non-updated files

I use WinSCP 4.3.5 on a Windows 7 portable.
I transfer files using FTP without encryption.
I use the commander GUI.
I connect to a server at OVH.
You can see the session log at https://pastebin.com/9iDKZMmF.

I do a lot of updates, copying local files to the remote server.
When I copy a complete directory, WinSCP always copies certain files, even when I indicated to only copy new or updated files and I just copied them.
The strange thing is that, when I go into the directory, I select the files separately and copy again, those files are not recopied.
I tried this both in automatic and binary transfer mode.

The correct link is https://pastebin.com/9iDKZMmF (without the dot).

I can see lot's of skipped files in the log, what would possibly indicate they were skipped for being "old". So it looks ok.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
