How Come the Site that Has A Link to my Blog Isn't Showing Up on Blogrolling.com

Tweet

I just opened an account with blogrolling.com. With that I'm able to see which other websites have linked back to me. I like this feature because it tells me who else is helping to promote my blog (believerinbalance.blogspot.com). However, I'm confused because I just successfully added a link back to my site on cafemom.com, but it's not showing up on my blogrolling list of websites that are linked back to me. While I understand (or think I do!) that having my blog LISTED with a website, is not the same as having it LINKED to my website, I thought what I did with cafemom.com was a LINK. Can somebody explain to me why my links aren't showing up on my blogrolling account? Thanks!
