Conquered French Skill Tree... Yet Again

According to the mobile app, I completed Duolingo's French skill tree yester-day.  I usually do French on the web version, though, where I still had to pass checkpoint 10, which I did this morning.  In any case, I conquered the French skill tree.

This is the third time I've done it now.  (Here's a link to a post about the second time.)  Duolingo keeps updating the skill tree and taking my trophy away.

Navajo Level 4 Trophy

I reached Navajo level 4 on Duolingo to-day:

I think I've said this every time I've levelled up in the Navajo course, but it bears repeating:  I don't know as much about Navajo as this would seem to indicate.  For one thing, the skill tree is pretty short, and most of the time, I'm guessing.
