It sounds like there is confusion on how the directories and download work together based on Sonarr and your news/torrent client. I did a visual flow of how the different directories and such work so it may be helpful to draw out the flow and where files are dropping and to what location so the mapping is clear. I’m primarily a Linux user as the concepts are the same so I used some example Windows paths.

Not quite a perfect wording/rendition, but I think it gets the idea across.
