Пользовательское метаполе WordPress не сохраняет все данные

У меня есть код ниже, чтобы добавить два отдельных мета-поля к моему типу записи. Первоначально у меня был только «свидетельский» метабокс, который работал нормально. Теперь я добавил «кредиты», которые хорошо отображаются в админке, но не сохраняются в базе данных?

Может ли кто-нибудь помочь, надеюсь, это ничего особенного.
