The forum members can't see what you added in the admin but looking at the site I'm going to guess. Let's see how we go!
The assumption is that you've added "instagram.com/grow.in.grace.boutique" as the url. This isn't a complete url.
"https://instagram.com/grow.in.grace.boutique" is, so try adding that (without the quotes of course!) in your settings instead. Same for the other social link you've got.
