The menu has a problem

I have a problem on the menu. It could be the problem in css code. The border doesn't work very well.
I upload an image.
Can you help me please?
Thank and regards

------ ---------------LINE 237 ---------------------------------
#menu .ddsmoothmenu li ul {
position:absolute;
left:0;
display:none;
visibility:hidden;
margin-top:19px;
margin-left:4px;
/*-moz-box-shadow:0px 0px 6px 3px #d6d7d6;*/
/*-webkit-box-shadow:0px 0px 6px 3px #d6d7d6;*/
/*box-shadow:0px 0px 6px 3px #d6d7d6;*/
}
------ ---------------LINE 153 ---------------------------------
#menu li.current-menu-item a, #menu li.current-menu-parent a, #menu li.current_page_parent a, #menu li a.selected, #menu li a:hover, #menu li.current_page_item a {

line-height:40px;
background-color:#fff;
