Counter is wrong in Multilingual site

My site is multilingual with 3 languages (english, spanish, basque).
Taxonomy menu's counter display number of nodes in any language.

For example if I have 1 content in term "Health", translated to spanish (and term "Salud" in spanish), counter displays:
in english version: Health (2)
in spanish version: Salud (2)

I expected to see only number of nodes in actual language.
In previous example, this will be:
in english version: Health (1)
in spanish version: Salud (1)

I attach multilingual options in this content type, vocabulary multilingual options and actual menu.

I really don't know if this will be a new feature or it is a bug. I hope you can help.
