You are using the chorus repeat number (for the entire song.) A loop (as we define it) is usually a smaller portion of the song (although you could loop the entire song.)
Click-drag from the first measure to the last measure you want to loop (could be as small as two measures.) The Play button will turn into a loop button - click it to start play.
