Удалить все карты действий из списка ссылок карт

Question

Я использовал объект карты для работы с которым я создал список ссылок игральной карты.

Из списка ссылок карт я пытаюсь удалить все карты действий. Но удаление узла или карты действий ничего не делает. Он всегда печатает все карты, не вынимая его.
