The display text for 明 (míng) in the lesson is "ming". When I highlight it and add to vocabulary, it still shows "ming". This is probably an error since it is definitely toned. Later, the display text for 静 (jìng) is jing, and 情 (qíng) is displayed as "qing". Right after that 晴 (qíng) is displayed as "qing".
