I looked further into the mapping and this was pretty much what was wrong. When I had changed the mapping in SANbzd, I didn't change the name of the path for unRAID. I left the name "/downloads" but the container path was actually "/data/usenet" (from following Trash Guides). So, the "/downloads" path mapping didn't exist, but that folder was selectable. Strange that the file would download and still be accessible through SMB to where I actually wanted it to download.
Now I can fix my other docker containers. I could not see the error until I actually clicked to edit the mapping that I made this error.
