your artist collection field group set appear on 1 post, post designer post 1 designer post type.

i don't understand code for? create different field group each post needs different field group , separate rule each.

ok sorry understand issue , have recreated issue on local install.

on line of code below looking post_parent think should looking id.

i changed this:

$post_parent = $post->post_parent; 

to this:

$post_parent = $post->id; 

and it's working me.
