issue with _ in post type

[jennafarr]

Thank you for this simple solution. It has worked very well however there is an issue with the display of the calendar when the post type has an _ in the name. I was able to trace the issue to this after seeing it work on other post types. Then I created another one with an _ in the name and could replicate the issue. Our example post type is day_camp and I am using the following snippet in functions:

$types = array( 'run', 'program', 'day_camp', 'home_slide' );
foreach( $types as $type ) {
	add_post_type_support( $type, 'unpublish' );
}

I've attached the screenshot displaying the behavior on that post type. I am not seeing any console errors, just the odd layout issue.

As an update to this. It was actually a conflict with ACF. When that plugin is not installed, the interface looks completely different and probably as you designed it to. Also - if the post does have an ACF date picker field, that takes over the unpublished date interface and then works. So this condition exists when you have ACF installed but no ACF date picker field on the post type.
