 // works correct

 $list = wp_get_object_terms([ 104627 ], [ 'produkte' ]);
 print_r($list);

 // returns all terms for produkte and herkunft and merges all terms
 related to the post

 $list = wp_get_object_terms([ 104627 ], [ 'produkte', 'herkunft' ]);
 print_r($list);

 Problem is unset( $taxonomies[ $index ] ) followed by $terms =
 array_merge( $terms, get_terms( $args ) );

 foreach ( $taxonomies as $index => $taxonomy ) {} iterates for all given
 taxonomies and leaves an empty  $taxonomies array. get_terms() with an
 empty array for $args['taxonomy'] returns "all" related terms and merges
 with the terms of the previews loop run.
