Программа не верно считает количество слов в тексте

Заметил две проблемы:

1. В выводе у меня появилось слово wa, хотя в тесте его нет.
2. Количество слов подсчитывается не верно.

File(В котором я вел подсчёт слов): https://dropmefiles.com/qAfrA

book = open('book.txt', encoding="utf8").read()

# lemmatisation words + lower register

lemmatized_output = [lemmatizer.lemmatize(w).lower() for word in list_text]
