"Vote Now" button appears when it should say "Save"

[Sussudio]

Just a heads up to the admins...this isn't a big deal of course, but sometimes when I go to edit my post, instead of saying "Save," the button has changed to "Vote Now" (though clicking on it still saves my newly edited post). This is not a consistent error as it seems to happen randomly. Wanted to make you guys aware, keep up the great work with the site
