Relational posts not showing in admin columns

Hi,

I've tested on my local site, the relationships and admin columns still display as well. Please see my screenshots

Could you please deactivate all plugins except Meta Box plugins then check the problem again?

Or you can test with sample relationships between posts and pages

add_action( 'mb_relationships_init', function() {
    MB_Relationships_API::register( [
        'id'   => 'posts_to_pages',
        'from' => [
            'object_type' => 'post',
            'post_type' => 'post',
            'meta_box'    => [
                'title' => 'Connect Pages',
                'priority' => 'high',                
            ],
            'admin_column' => 'after title',  // THIS!           
        ],
        'to'   => [
            'object_type' => 'post',
            'post_type' => 'page',
            'meta_box'    => [
                'title' => 'Connect Posts',
                'priority' => 'high',
            ],
            'admin_column' => 'after title',  // THIS!        
        ],
    ] );
} );

Hi,

The problem is the slug of post type, it should be 'post_type' => 'aandoening', not the singular name Aandoening. Please change the relationship code and check the admin column again.

Hi,

Does that mean the Quick Edit option? https://cl.ly/da7757a7bb53

I will discuss this with the developer team to create a new feature to support this case. Thanks for the idea.

Hi,

Currently, we are researching and developing feature supports to change the value of Admin columns in Quick Edit. If you really want to make the admin columns editable, please try to use the plugin Admin Columns and their addon Meta Box Integration.

Thank you.
