I’ve managed to get the code to work, but doesnt’ seem like the post_object type that I’ve created matches the Post Object type from the ACF Field creation admin.

Here’s the code:

if( function_exists('acf_add_local_field_group') ):

acf_add_local_field_group(array (
	'key' => 'group_1',
		'title' => 'My Group',
		'location' => array (
			array (
				array (
					'param' => 'options_page',
					'operator' => '==',
					'value' => 'acf-options',
				),
			),
		),
	'menu_order' => 0,
	'position' => 'normal',
	'style' => 'default',
	'label_placement' => 'top',
	'instruction_placement' => 'label',
	'hide_on_screen' => '',
	
));

acf_add_local_field( array(
	/* (string) Unique identifier for the field. Must begin with 'field_' */
		'key' => 'field_1',
		
		/* (string) Visible when editing the field value */
		'label' => 'Sub Title',
		
		/* (string) Used to save and load data. Single word, no spaces. Underscores and dashes allowed */
		'name' => 'sub_title',
		
		/* (string) Type of field (text, textarea, image, etc) */
		'type' => 'post_object',

		'parent' => 'group_1',
		
		/* (string) Instructions for authors. Shown when submitting data */
		'instructions' => '',
		
		/* (int) Whether or not the field value is required. Defaults to 0 */
		'required' => 0,
		
		/* (mixed) Conditionally hide or show this field based on other field's values. 
		Best to use the ACF UI and export to understand the array structure. Defaults to 0 */
		'conditional_logic' => 0,
		
		/* (array) An array of attributes given to the field element */
		'wrapper' => array (
			'width' => '',
			'class' => '',
			'id' => '',
		),
		
	/* (mixed) A default value used by ACF if no value has yet been saved */
	'default_value' => '',
	
	/* (mixed) Specify an array of post types to filter the available choices. Defaults to '' */
	'post_type' => 'post',
	
	/* (mixed) Specify an array of taxonomies to filter the available choices. Defaults to '' */
	'taxonomy' => '',
	
	/* (bool) Allow a null (blank) value to be selected. Defaults to 0 */
	'allow_null' => 0,
	
	/* (bool) Allow mulitple choices to be selected. Defaults to 0 */
	'multiple' => 0,
	
	/* (string) Specify the type of value returned by get_field(). Defaults to 'object'.
	Choices of 'object' (Post object) or 'id' (Post ID) */
	'return_format' => 'object',
) );

endif;

The first one allows multiple selections, the second one does not. Change this to 1

/* (bool) Allow mulitple choices to be selected. Defaults to 0 */
'multiple' => 0,
