Non-existing remote folders getting synchronized

So, I updated to 5.19.1 (Build 11552) today on my Win 10 machine and I'm connecting to a remote FTP that worked for me before.

Now I see a folder "/<previous level>" and "/<path from root" on the remote.
The <previous level> always shows the previous folder, for example if I have
'/root/sites/contact' and I'm in 'contact' it will show "/root/sites".
The <path from root> at the same time will show the path to the current folder, for the example above "/rot/sites/contact"

Problem is that the program tries to synchronize these virtual remote folders and throws errors and creates these folders on my local folder.

What version were you using before?

Please attach a full session log file showing the problem (using the latest version of WinSCP).

Previous version was 5.17.10

As requested. I replaced all private parts with [redacted], I hope I got them all.

Imo, it's a bug in the server. But ok, since the previous versions of WinSCP were compatible, I've restored the compatibility:

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