Заголовок заголовка таблицы iOS не останется на вершине обзора

Как следует из названия, заголовок раздела, который у меня есть в моей таблице, когда прокрутка не будет оставаться на вершине. Он работал раньше, но по какой-то причине он прекратился. Я не могу понять, почему за жизнь меня. Любая помощь была бы потрясающей. Благодарю.

Код:
