That is not right at all
So I am on the level 10 in Dutch
so to make the long story short it is displayed here:
but not here:
I think it's a glitch with some users that Duolingo is currently trying to fix (and has, already, partially fixed now). Right now, I can see your Dutch badge and I can see mine, but I guess the "phantom badge" happens to some users in some of the discussions (sometimes I still can't see my Dutch badge in a comment I make).
EDIT: I looked at your comment again and it's disappeared (but I can still see mine).
