This shows your files were imported, not indexed. This fact and the missing Files.noindex folder means you don’t have an intact database restored.
While we don’t do support for services, like BackBlaze, it may even be that you have never been backing up a full copy of the database. Some services have excluded folders or locations in their backups.
If you haven’t emptied your system Trash, the database may still be in it.
And where exactly does these folders or locations should be when when the files are imported in DT? I can search if I can restored those from BackBlaze.
This is showing the internals of a database. Whether that’s actually inside a .dtBase2 file or whether you restored these items separately is unclear from your cropped screen capture.
Inside a .dtBase2 file, you would have the items shown and a Files.noindex directory.
