No .. in panel after connecting specific sftp server

Hello, I have an issue with displaying .. on one of the company's local sftp servers, when I enter any folder, if it does contain any sub-elements (files or other sub-folders), then no .. for upper level navigation is displayed, and only if folder is empty then .. is displayed. Is this a known issue with Winscp/sftp servers/some configuration of both, or something new? If second, what information do you need to investigate and resolve it?

WinSCP indeed won't display the ".." entry, if the SFTP server does not include it in the directory listing (most do include it).

I have sent you an email with a development version of WinSCP to address you have used to register on this forum.
