Facebook add question?

So I added someone on facebook, but when I checked like an hour later the option to add the again reappeared. I realize this normally means that someone declined your friend request. But then I noticed that when I was not on their page, but on a page to make their name pop up (like how you can click the list of people who liked a post) the option there it still says friend request sent. Is this a glitch? Or what?

yeah, sounds like a glitch
