The presentation of projects is defined in the template. The project category “Coming Soon” should now not be displayed in the upper area. The code was added to lines 31 to 37:

'meta_query' => array(
                array(
                    'key'     => 'project_kategorie',
                    'value'   => 'Coming Soon',
                    'compare' => 'NOT LIKE'
                )
            )

However, the “Coming Soon” category should be displayed again at the bottom (from line 140).

Here is the complete template:
