Japanese showing wrong characters

[Alex149257]

In Japanese Hiragana 2, Lesson 1 and 2, Duolingo showed options in matching for characters I haven't learned and didn't show the words for the translation, what do I do to fix this?

Example for Lesson 2:
Characters/words for lesson: や, け, の, やさい, おさけ, のむ
Matching: ni ら ra け ko こ ma まに ke
Characters not learned: らまこ

That’s because they’re having you exercise old characters in addition to learning new ones. This will happen with words too. It’s not a bug.

Actually no, they test on characters that haven’t yet been introduced.

They're showing characters that weren't introduced before, but in 3 Lessons after that one. For example, you don't learn ら until Hiragana 2, Lesson 5 and it is showing up in Lesson 2.
