help with links for menu items

I have a Staff section (parent page) with individual Staff bios (child pages) on a website I am working on but in my menu, the parent Staff section is clickable and links to the Staff page. I want to make it so Staff is not clickable and does not link to anything so a user will be forced to select a specific child page from the drop down instead. As a workaround, I placed a gallery with a photo of each staff member on the Staff page and I tried to link each individual photo in the gallery on the Staff page to their bio but every time I update the link, it reverts back to the link to the picture so I can’t link to the bio pages. Is this a glitch? Thanks in advance for any help you can provide.

Example is at http://studio.mbrs.us, the menu in the upper left. I want “Staff” to not link to anything, but show up in the menu.
