Entity information not shown using Appdaemon in Docker

I have installed Appdaemon in Docker (docker compose), created apps and dashboards which all run as expected and can access entities / state etc through the API calls. If I access the Appdaemon page I can see the dashboards I have created, clicking on State I can see the apps, plugins, threads and callbacks as expected, however clicking the Entities tab within State doesn’t show anything - if I remember correctly when I had Appdaemon running as an addon on a RPi this showed the state and attributes of the entities, is there a setting that I need to be able to show the entities or is this not available with Appdaemon in Docker?
