iPod touch Bizarre language problem on iPod Touch

I've got a 4th generation iPod Touch. I had a problem with no music showing up on the library. One of the suggested fixes I found was to change the language settings to a different language, and then back to English. I did that. I changed the language to French and then back to English. But now some of the apps, including e-mail, still display in French. I've got the language set to English but (1) when I swipe to the right from the main screen to get the search screen, the space bar is labeled "espace" and the return key is called "Rechercher." In mail, I also have an "espace" key and a "retour" key. Any idea how to get these back to English?

Update -- I tried changing the language to German and back to English. The keyboards are still in French (with both the German and English settings).

Thanks - that did it. In the keyboard settings it showed English, French and German. Strange that the overall language setting did not change the keyboard from French, but I deleted the French and German keyboards and now it's back to English.
