last child menu underline alignment off

Hey, I had to modify the css below from left 7% to left 0 (see below) in order to get the underline under the last menu item to line up properly on http://www.teamabi.com/wordpress — I think this is just an FYI for you guys, but let me know if I’m missing something (if this might mess something else up that I’m not noticing). And let me know if there’s a better place to post things like this. Thanks!

.html_header_searchicon_disabled #top .main_menu .menu > li:last-child > a .avia-menu-fx {
    left: 0;
}
