PayPal button explodes and buttons misaligned

I have installed VeBailovity's update 1.0.1a to solve a problem with Thesis, but there are still a couple of problems with the page.

I added myself as an attendee to the test event. After doing so, the dialogue that shows you need to pay and links to PayPal shows up, but the PayPal button is enormous and the No Maybe I'm Attending buttons are misaligned. Attached screenshot.

Also, is there a way to REMOVE an attendee once they've signed up?

Help appreciated.
