Page not Showing in Drop Down Menu

[sharlapatrick]

I have the Allure theme and I LOVE IT...

For some reason though I have a Parent Page (titled-Events) that has 5 "sub" event pages that should be listed in the drop down menu. 4 out of the 5 sub pages show but not the first one.

This just recently happened...and I've changed nothing. It did used to be at the top of the list like it should be. I've checked everything in the admin area and it appears fine but the page isn't listed (the page missing under events is Oklahoma Leadership Summit.

(what's really strange is the page does exists because if I check on the page through my admin area the page pulls up just fine-and this particular page is also listed in my gallery and if I click on that picture in the gallery the page pulls up-but again, it's not accessible through the menu which obviously I need.)
PLEASE HELP ME!!!
