Why don't I see "Type" In My Wordpress Gallery?

I came upon this article today and am really confused because I don't see this option when I create (or edit) galleries in my wordpress site.

The below article shows all of these options that just don't exist for me.

A) There's nothing related to image carousel's in settings/media.

B) When I create a gallery in wordpress there is no "type" option with default, tiles, square tiles, circles or slideshow.'

I'm totally confused. I turned off as many plugins as I could - I hope it has nothing to do with that. OR, is it possible that this is the new wordpress? If so, is there a way to get access to this earlier?
