Current behavior

I have added templates for PR a few months ago but I've never seen them when opening a new PR. GH shows on this page that it does not detect the templates.

Expected behavior

A list of PR templates should be displayed when opening a PR.

Anything else?

Does GH really support multiple templates for PRs?
