Hi, I think that there is a bug in the iOS version of Duolingo app.

So I have my coach turned to the 'Insane mode' so I have to gain 50 XPs to have my coach goal achieved.

Today I decided to start my practice from Dueling and gained 11XPs and when I looked at the balls that are visible after we practice they were green. (As far as I know it means that you have completed your coach goal) But I have gained only 11 XPs out of 50 XPs so the balls should be yellow instead of green.

I could have been mistaken and wouldn't have practiced any more if I hadn't noticed that.

Here are the screenshots of the problem:
