SMS Unread Message Counter Not Showing

I have 5.1.1 on my 4s. Aren't I supposed to have an unread counter on my SMS app badge in the homescreen (like the mail app)? I am using BiteSMS and Lockinfo. Is one of them making the unread counter disappear? I can't seem to get it to show up. I'd like to see it have the counter on if I hit 'later' in the BiteSMS quickreply. Any suggestions? I haven't had an iPhone for a year or so and can't remember if there's supposed to be an unread counter but I thought so (?). Thanks
