Bug copying files to "network ressources" copies files to local drive

I mentioned a serious bug. I added various shares of my NAS to my explorer. As I don't want my windows explorer to be overloaded with various "network drives" (with drive letter!) I added some rarely needed shares via "network ressource" (without drive letter). Network ressources can be found in userprofile here: %USERPROFILE%\\AppData\Roaming\Microsoft\Windows\Network Shortcuts.
Now copying files from your local drive to this network ressource does NOT copy these files to the network share itself, but onto %USERPROFILE%\\AppData\Roaming\Microsoft\Windows\Network Shortcuts\<NetworkShortcut>\ and the file is still located onto local hard drive. Please see this screenshot:
