Custom post type not being targeted

I just installed the plugin on my site that uses a custom post type. I have added some checklist items and I see them on the generic post editor. However I have selected the custom post type on this screen: /wp-admin/admin.php?page=ppch-settings and clicked save. But when I create a new post of that custom type, the checklist interface is missing.

Can you tell me what I am doing wrong? What should I do to troubleshoot this? I have debugging on and there are no errors.

The checklists I have added are:

• number of characters in excerpt (50-250)
• Feature image is added

The custom post type has both excerpts and featured images options

The following is the custom code that creates the custom post type:

/*

add_action( 'init', 'cdf_events_register_post_type' );
function cdf_events_register_post_type() {
