Change the settings on the top menu xili language picker

I have changed the settings on the top menu screenshot – http://puu.sh/l1NlQ/d9313556bb.png
And now my website do not translate on the different languages, shows only this language that I chosen.
Earlier everything was fine, the site was showing in a language of the visitor browser.

Please help, how can I fix this?
