No it's not
You error states unable to import xxx from /data/.....
You can tell deluge to download to /downloads, but since you don't have /downloads mapped in the template, it winds up being stored within it's image, and doesn't matter what you do but sab will never have access to it.
Change the container path for /data in deluge to be /downloads
But, deluge (and Sab) may remember the original download path you had set when you queued up files (if it was originally set to use /data in its settings)
