Горизонтальный RecyclerView не прокручивается влево после SCROLL_STATE_IDLE

Question

Я создаю вложенное горизонтальное представление переработчика для указания списка категорий во фрагменте. Я все настроил правильно (см. Код ниже). Тем не менее, когда я прокручиваю изначально, и просмотр рециркулятора переходит к SCROLL_STATE_IDLE, я не могу прокрутить в противоположном направлении.

Но , если я продолжу прокручивать вправо, то go влево, не поднимая мой палец работает нормально. Не уверен, почему просмотрщик мусора застревает.
