Sub-Menu Troubles

The sub-menus on my theme are not working correctly on the desktop version of the GovPress theme. It works correctly on the mobile version.

To see what is happening, please visit http://www.narberthpa.gov and click on “Contact Us/Borough Staff” to see the problem with the sub-menu. I have created a page named “Test Page”, and have it’s parent page defined as “Borough Staff”. I have it located as a sub-menu to “Borough Staff” in the menu configuration, but cannot figure out why it is hovering.
