Need help with Widgets Overlapping

This doesn't involve themes or plugins from wpmudev but I am hoping for some assistance from the many experts here. I am using Citizen Kane theme with buddypress 1.28 and wordpress 3.1.4. I have everything working but there is one issue that I cannot figure out with the widgets on the front page. Anytime I place an "Authors Grid" widget or "Friends" widget (anything that shows avatars in a row) the widget below it bleeds into it if there are not enough avatars to fill the row.

Again I know this isn't specific to themes or widgets from you guys and I appreciate any info that can be provided.

My site is and I have left examples of this on the home page to show what is going on.
