My org-mode files are rendered as if they were markdown, why?

I’m trying to render org-mode text files in Hugo, I believe Hugo uses go-org and should render content files as org-mode to HTML if they have an .org extension … but this doesn’t seem to be the case.

E.g. I have a Org content file with the following content:

#+title: Org Test
#+date: 2020-02-08
#+draft: false

* This should be a header

# This should not be a header

Which renders as if its markdown like so:


I’m using Hugo v0.62.2.

If you have a minimal reproducible example, you should open an issue on the Hugo repo and cc the go-org developer.
