stacks become limited after reboot

No matter what I do, I can't get stacks created in portainer to stay editable over a reboot. docker-compose.yaml is simple enough

  portainer:
    image: portainer/portainer-ce
    container_name: portainer
    restart: always
    ports:
      - 9003:9443
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /vol/raid/data/portainer:/data
    labels:
      proxy.portainer.scheme: https # set it to proxy to https
      proxy.portainer.no_tls_verify: true # disable TLS, assuming app is using self signed cert and maintains only local connection

the path to the volume (and all subdirectories) have root.root as owner, permissions 700, the docker-compose.yml files are 600.

I create the stack via web interface, control is "total", reboot, control becomes "limited". Not sure what to do here..
