BUG – save_post hook triggers twice

Anytime a Post is saved or published, WordPress is designed to trigger the save_post Hook only one (1) time. However, when the ConvertKit plugin is enabled, it causes the save_post Hook to trigger two (2) times.

PLUGIN VERSION TESTED:
Version 1.9.4

STEPS TO REPRODUCE:
Add the following to function.php:

add_action( 'save_post', function($post_id, $post, $update) {
    // Avoid auto-saves
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;

    error_log("save_post hook triggered");
}, 10, 3 );

Compare the PHP error.log before & after the ConvertKit plugin is enabled.

NOTES:
Commenting out add_action( 'add_meta_boxes_post', array( __CLASS__, 'add_meta_boxes' ) );
in file plugins/convertkit/includes/class-convertkit.php:71 fixes the issue.
