Events Manager – Widget sizing issue

Hello,

I really like the Events Manager plugin and want to use it on my site. But for some reason, when I add the calendar widget to the right panel, it re-sizes the calendar down to about half as big as it should be. Take a peek here: shepherdofthehillsomaha.org .

Any ideas as to how I may be able to adjust the code to make it fit better?

Thanks,
JT
