Hi,

in the french interface I have the right amount of english known words (http://imgur.com/zNYjs3G,rVVwpzK#1) but in the english interface I have 0 instead of the right number (http://imgur.com/zNYjs3G,rVVwpzK#0).

I would have understand if I had:

• in french interface : only english non zero, since I learn english only from french
• in french interface : only english (and italian that I don't learn) at zero, since I'm not learning english from english.

But it seems the count/display is not interface depending, so I guess it's a little bug.
