For some reason i have 3 Collection libraries, instead of 1 - not sure how this has occurred.
I'm running embyserver in a docker container on unraid OS.
is there anywhere in emby config i can remove these, or reset to default - i.e. 1.
many thanks
You have to shut down Emby, delete the Collections options.xml via Emby Programdata path */root/default/collections, start Emby and you will see Collections library is now Mixed Content and you delete/remove Collections which causes a library scan and new corrected Collection it any Collections still exist.
Sorry don't know Docker paths.
