java.lang.IllegalArgumentException: viewType is not valid в MultiTypeExpandableRecyclerView

Я пытаюсь сделать приложение "To do list". В нем мне надо использовать MultiTypeExpandableRecyclerView, но что-то у меня с ним не складывается.

Полный проект YANDEX DISK. Использую это библиотеку КЛИКЛ(github).
