this is caused because of your CSS Insert
HTML Code:
ul.rMenu li {
position:relative;
left:198px;
}
this causes all <li>'s under the rMenu to be shifted. The sub menu is also an <li> so it also gets shifted the 198px. You need another CSS insert to unshift the <li>'s in the sub-menu's. Try this
HTML Code:
ul.rMenu li ul.rMenu-ver li{
left:0px;
border: solid 1px red;
}
