Wrong hiragana is highlighted for kanji testing

In some of the example sentences for the kanji game, the wrong hiragana appears as highlighted (magenta) text. For example: だれもないはそのはなしをしらない。(or something like that). And the highlighted portion was the "らな" part of しらない, and the "correct" answer among the kanji was 話. The sentences might need another review by the creators to make sure all the answers line up correctly.
