Topics marked internal in `_pkgdown.yml` still show up

Topics marked internal in _pkgdown.yml still show up in the reference index. Note that the title "internal" doesn't show up, but the contents still do.

I might just be misunderstanding the docs - but from what I was reading I didn't need to add @keyword internal to the functions, all that was needed was adjusting the .yml file.

Relevant section of _pkgdown.yml (at the bottom):

- title: internal
- contents:
  - arrange_across.
  - mutate_across.
  - summarize_across.
  - case.
  - get_dummies.
  - ifelse.
  - inv_gc
  - top_n.
