Одно и то же свойство для одинаковых объектов появляется дважды

У меня есть объект ($ узел). Мне нужно обновить значение свойства объекта, сначала я сбрасываю его, а затем обновляю

  unset($node->field_the_tranasction_status‎[LANGUAGE_NONE][0]);
$node->field_the_tranasction_status‎[LANGUAGE_NONE][0]['tid']=97;

Тем не менее, если я печатаю объект $ node впоследствии, используя print_r ($ node), свойство field_the_tranasction_status появляется дважды следующим образом, и это вызывает проблемы при вызове функции save ():
