Tap test is always wrong no matter what I do

I’m using Google chrome on this level: http://www.memrise.com/course/584/jlpt-n4-vocab/43/

THe word I’m trying to learn is 上手い;巧い

I put this in correctly every time, but the game marks it wrong every time. Here is a screenshot" https://i.imgur.com/5g0SJnC.png

I believe this has also happened on other words, but I can’t remember which.

Similar bugs have been brought up for tapping tests on the web.

Are those similar to your problem?

It seems like the first one is more something being marked correct that shouldn’t, and the second one is more the words being in a different format than expected. On mine, I’m able to input the exact correct answer, but it says I failed anyway.
