Well, I can't see the French flag here but it shows up in your profile. Don't worry about the flags, I guess it's kinda buggy when users are taking multiple courses.

(11 Dec 14) In the past week or two, I've noticed that my French level (as shown in discussion posts) is one level above what my actual Spanish-to-French level is, even though my English-to-French level is several levels higher. I've also noticed that when I add a new post to a discussion, the levels (for all posts in that thread) show correctly, but when I go back to them later, the level is back down to its previous level (too low).

EDIT (2:39 PM PST, 11 Dec 14): For example, for this post, the flags appeared normally 38 minutes ago when I first made it. Now that I've browsed around and returned, the French flag is incorrect again (should be 9).

Writing this after your second edit: I only see your Spanish and English flags.

Thanks for the replies (a lingot each for your services!). Now (10:32 PM PST 22 Nov; 06:32 UTC 23 Nov), again, I don't see the French flag on this discussion.

EDIT: And a page refesh (Ctrl-F5), and it's there again. (Refreshing doesn't always work, though.)

Still no French flag. Does it have your levels right for the other two? On mine it was saying I was level 13 in German when I was only 12, and that I was level 2 in English when I'm level 4 or 5. There is definitely something wrong with the flag-level interface.
