Addon Help - Sidebar Rendering Issue

Hi,
I’ve been working on updating the addon for Traefik, as the original repo i found is read-only and deploys a much older version.

I’ve got v3.3.4 deploying on my HA, but for the life of me i can’t get the sidebar to render the Traefik dashboard correctly. Am i missing something obvious here?

Example -

If i expose the port so i can access the dashboard directly, everything renders correctly.

Has anyone come across this before?

Thanks!

Looking at Chrome’s dev tools, i see a lot of these, for each of the sections in Traefik -
