Help please 
Alright I did what was suggested with the whole 4K library, basically creating 1080p optimized versions. Now as it seems the transcoder is still using the 2160p version and therefore my ability to serve multiple transcodes as soon as a 4K file is streamed is almost gone.
Below you find the excerpt from the PlexMediaServer.log. The device used is my Nexus 5X. I didn’t choose any version and set the quality to 4Mbps 720p before hitting that play button.
I am providing the xml file of the played tv show episode as an attachment. There you can clearly see, that PMS has an optimized version available 1080p universal mobile with 8055 kbps.
Why is the transcoder still picking up the 4K video and transcodes it to 720p?
