actually, just tried it again on another production site and my solution / the bug in question does not exist.

So probably best to disregard the above as a general problem/fix

Thanks for the reply. Sorry for missing the obvious !

Just to say I encountered the same problem (3.5.1)

Additionally,
‘show’ => ‘false’,
‘context’ => ‘advanced’
… also have no visible either on my setup.

I guess the quickfix is to set the css to display:none
The id used to identify the admin box is unique depending on what posttype you are editing. So easy!
#p2p-to-Session_to_Abstract
#p2p-from-Session_to_Abstract

This filter works but removes all admin boxes which isnt quite what I want.
e.g.
function restrict_p2p_box_display( $show, $ctype, $post ) {
if ( ‘ConnectionName’ == $ctype->name && ‘to’ == $ctype->get_direction() ) {
return 1;
}

return 0;
}
