Рекурсивный вызов функции. Повторный запуск "помнит" значения

Есть несколько словарей. Нужно перебирая по словарь final_list_LN или final_list_matches_AM подтягивать из словарей list_sheet_param_val и list_sheet_param соответствующие значения ключей и формировать списки.

Попытался реализовать при помощи рекусрии. Получается то что нужно, но только если вызвать функцию один раз. Но почему то в списках присутствуют дубликаты, кототрые удаляю другой функцией (def f(l)). "do" - результат работы рекурсии "posle" - результат удаление дубликатов в "do":
