View Mode not showing up under Manage Display I created a view mode let's call as my_node_view for content type under display type settings, I was expecting it to show along with default and teaser tabs as default|teaser|my_node_view in manage display section, but it did not show up. I have ensured my_node_view is checked under custom display settings for Use custom display settings for the following modes. Am I missing anything?
Writing out my comment as an answer.

This apparently needs a manual cache clear right now to work.
