Multi-day Events

I have a grid calendar on this page, as well as a list calendar in my footer. Everything works fine, unless I have multi-day events. They display properly on the grid calendar but not on the list calendar, however when I hover over the event on the grid calendar, the first day will show the correct time frame but the days after that extend the time frame by number of days the event takes place from each day. In the list calendar it then shows the single event as two or three separate events, each extending the time frame by a day. Could you look into this and see what may be going wrong?
