Recent Comments Block display

Hi, I just tried out this module and instantly fell in love with it.
One thing I can't get to work though is a display of the block on my page. It just breaks it and separates the title from the actual content in the block. Title is showing normally, but Recent Comments in my sidebar show up only after Main Content region ends at the bottom. See the screen shot I attached.

I'll try to mess around with CSS, but if someone could point me towards the right spot, that would be greatly appreciated.
