Remote file already exists ( but it does not )

Winscp version:

Trying to transfer few files to remote server but already existing error message pops up (but remote folder is empty).
Any feedback much appreciated.

Please upgrade to the latest version first.

If it does not fix the problem, please post a complete session log file (and less verbose for a start).
