Events+ Styling Is Wacky

Hi I love the Events+ plugin and its the reason why I became a member. The problem is the styling of the calendar must have some kind of clash with the theme I'm using because it doesn't display right. Please see the two pages below:

-http://myistanbul.org/calendar - When you hover over an event, it doesn't show up right:
-http://myistanbul.org/groups/basketball/group-events/ - It doesn't look right at all.

If anyone can give some instructions on how to fix these, I would really appreciate it.
