Desktop App for 6.0.3 Windows 11/10 23 synchronization problem

Good morning, I’m having a problem with the OwnCloud sync app when working with it on Windows and mobile phones. The problem is as follows: if I create a folder through Windows and rename it on the phone, the folder becomes visible only for phone use. Or, if I create a folder behind the phone app and put its contents there, the Windows program sees the created folder but doesn’t download it to Windows, even when forcing sync. If I download it from the stored website and put it in the folder with the others, it duplicates the folder using the same name on the phones. Can anyone help me with this?
