Listening Skills choice repetition too high

Platform: Android
Course: Mandarin 1

In the “Listening Skills” game, 3 words are available. I’d say more than 70% of the time, 2 of the words are “Ni” and “NiHao” which were learnt very early on.

This is a bug because it makes it way too easy to guess which of the words is correct just by elimination.

Cheers,
Matt.
