unable to link to projects page in menu

Hello

Why under >Appearance >Menu

are all my pages being listed under "Projects"

And why can I not list this page in my main menu:

http://missionimpactalliance.org/project-list/our-projects/

Which is being linked to from the CURRENT PROJECTS container on the homepage.

I have listed this in my main menu (a page which i have now deleted), but it is more or less worthless. I need to link to the actual projects page:

http://missionimpactalliance.org/our-projects/

Thank you for your help!
