https://stats.wikimedia.org/v2 looks great, but I have some issues with the localization. The main text of the page seems to not be localized (that is ok, I do not need it), but the search seems to be localized. So If I want to get the statstics for enwiki, I type "en" on the search bar, but I do not get enwiki. To get enwiki, I have to type "in", (inglés), English in Spanish. Technically this is my fault for my browser preferences, but I would expect to either have most of the things localized, or only in English, but not both. In particular, if I type "en" on the search bar for language, I would expect the English language to show up, no matter the language of my browser.

If I type "enwiki", I would expect to get directly the Wikipedia in English, as an advanced user.
