Home/Landing Page not listed on Wordpress???

This one really has me stumped...

I'm finally making progress with Upfront and want to make the first tab on my menu bar link to the home/landing page I've been working on. The problem... It is not listed on Wordpress?!? :open_mouth:

Now, I've found a way to add the link I want using the URL option for Upfront. But I'm still wondering about this. I've looked at all of the pages listed under "Pages" on my Dashboard. None of them is my home page. Is this something that happens with Upfront? Or is there something that I need to fix? And if so... How?
