Duolingo's software cannot differentiate between Qatlh and qatlh and pulls up the hints for both. It's supposed to put the hints that match the current sentence at the top, but sometimes fails at that. By any chance, do you have a screen cap of that?
If you see something like that again, we'd appreciate a screen cap of it. Our back end shows something different than what you have described and it would help us show the programmers what the problem is.
