Tree Menu Bullet Issue!

I am trying to figure out why on this page: http://arf35.com/

The sidebar dropdown menu (which as done in a simple tree menu) list items’ bullet point appears to move down to the middle of the list when there are other drop down items under the first list item. The bullet should stay at the top where the parent of the drop down list occurs, but when a user clicks it, it moves, and just doesn’t look right. For example, on the Los Angeles one, when you click it, the bullet point displays by the Montebello list item, as if there is another drop down, which may confuse some people. Can anyone take a look and tell me what is wrong so I can fix it?
