UIActionSheet is not showing separator on the last item on iOS 7 GM

UIActionSheet is not showing separator on the last item on iOS 7 GM

It could be probably a bug on iOS7. But the last button is not separated
from the previous one
As you can see from the image. This happens on both Simulator and device
using iOS7 GM. Does everyone else has the same problem?
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:@"Title"
delegate:self
cancelButtonTitle:nil
destructiveButtonTitle:nil
otherButtonTitles:@"First", @"Second",
@"Third", @"Fourth", nil];
actionSheet.actionSheetStyle = UIBarStyleBlackOpaque;
[actionSheet showInView:self.view];
As you can see the code is quite simple. Any idea on how to fix the
problem? Or some third party library I can use instead of UIActionSheet?
Thanks, Regards
