Regarding your UNC path recognition issue, you may want to refer to this article and lower your security privileges:

As for your empty folders, you could try specifically configuring the settings to copy such folders when found under:
Modify > Expert > Decisions-Files > Folders
Note that the settings in this Folders page relates only to how empty folders & case changes are handled. Instead of Automatic, you could specify the action to create such folders on the other side when found.
However, do note that we do not natively support WebDAV so it's not clear if such settings will work on them (but they certainly will for typical internal/external drives, network paths, etc)
