Docker: TV Show Images Changing to Defaults

[d90 11]

I have emby set up in docker on an ubuntu server. I have set it up with the instructions on docker hub. I'm also not new to docker. Been using a few years now. 

 

I like to change the cover art of my TV shows, especially ones that have aired for a long time so that I see the relevant actors that are still on the show. I change them, and they show as changed in the media server, and subsequently on my connected devices including emby for kodi practically instantly. Some time later, the images change back to defaults. I'm wondering why this is, and if I need to possibly map another volume to permanent disk space to facilitate this. Below is my compose info

    emby:
        image: "emby/embyserver:latest"
        restart: always
        container_name: "emby"

        ports:
            - "8096:8096"
            - "8920:8920"

        volumes:
            - /home/docker/emby/config:/config
            - /mnt/nfs/TV:/tvshows
            - /mnt/nfs/Movies:/movies

        environment:
            - UID=1000
            - GID=1000
            - TZ=America/New_York

Sorry. I was away for the weekend. A good example is Arrow.

This is the pic it keeps going back to. 

 

 

 

This is an example of what I'm trying to change it to. 

 

 

I've gone through many times and changed this one in particular. In Emby server I go to edit images and this flips back

I'm guessing the image that it keeps changing to is what is located in your series folder, right?
