After changing menu line height, submenu is no longer attached to menu bar

I decreased the menu height, and now my sub menus are disconnected and floating way below the my menu. Is there a way to re-align the submenu with the main menu manually? I altered the line height of my menu via: #header #mainmenu ul li a { padding: 0 25px; line-height: 25px; font-size: 15px; font-weight: bold; } Here is my site so you can see the issue: http://northwesturbanfarmer.com
