I have been struggling with the installation of SickRage and Radarr on the same machine and how to implement Transmission to manage trackers on the same OMV system. I now have a solution and wrote an entire blog-entry surrounding these issues and how to overcome them.
Basically in a nutshell, if you run transmission on the same environment as SickRage and Radarr, you will get into the situation where a movie gets logged as a TV episode and vise-versa.
To overcome this, I run two instances of Transmission on the same OMV machine, separating the watch, download, incomplete and complete folders. The drawback is that there will be two instances of Transmission running, but with today's technology should not be a problem.

kind regards and I hope the blog assists anyone struggling with the concept of running 2 transmission instances...
