Page widget styling problem.

I'm trying to get the collapsing pages widget plugin displaying correctly but I keep running into the same issue where the left border for the category link extends all the way to the bottom of the listing. That description is very vague but I can't think of any better way to describe the problem. You can look on www.pvpgamer.com at the menu on the right side named "Game Resources" to see what I'm talking about.

I've noticed that the default page widget displays the borders in the correct manner but if I add a "custom menu" widget it will have the same formatting problems that the collapsing pages plugin is having.

In any case any help would be appreciated as I've been knocking my head against this for about 5 hours now and I'm still clueless as to what the problem is. Thanks in advance.
