missing argument php error from wp Types plugin on maintenance admin page

Hi,

I really love this plugin and havent had any problems with it. I use wp types on a few of my sites, and iv noticed that when i go to the admin page of maintenance there is a php error that displays:

Warning: Missing argument 2 for wpcf_admin_add_meta_boxes() in /clientdata/apache-www/m/a/mywesbite.com.au/www/wp-content/plugins/wp-types/embedded/admin.php on line 101

This doesnt really affect me, at least i cant see how it is. because its simply stating that an admin field created by types is not rendering or something. but i dont even need that on this page, but i dont even need it on the maintenance page. So there is no real problem, i thought id just let you know.

I posted this on both the types support forum and on the maintenance plugin forum. here is the link to the types thread.
