Getting an error when an existing post type is mapped but saved with out any of the fields added. This breaks the field select functionality, requiring the post mapping to be deleted & recreated:

Warning: in_array() expects parameter 2 to be array, null given in \wp-content\plugins\post-my-contact-form-7\includes\class-cf7-2-post-factory.php on line 704
