Switch from dvorak to qwerty layout

 I'm trying to switch from dvorak to qwerty layout. I've tried to follow the instructions, but when I click on a language, there's nothing to scroll; no layout options. If I click the globe, then click a language, a keyboard appears with a green dot on it with a check in the middle and it says dvorak on the bottom.

No matter what I try the layout won't change. Any help would be appreciated.
