Lost "Save and keep published"

I’ve just upgraded my site from the lightning build 1.14 to 2.06 and in the process, I’ve lost “Save and keep published” from the content types to simply “Save”. By allowing moderation on the content type, I get a “Moderation state” dropdown with different states in, but that appears half way up the page and I can’t move it down as it doesn’t appear in the the “manage form display” form.

Full disclosure, I’m very new at Drupal and it’s a site I’ve taken over from someone who has left the company. It wasn’t installed or maintained using Composer (seemingly) so I’ve updated it manually by copying across the core and profile/lightning directories.

Can anyone help me? Thanks in advance.
