I'm having 2 issues with K2 content and how it's being displayed:

 

The first is a menu item of type K2 » Itemlist / Category.  For some reason, some of the items are being displayed side-by-side instead of in a vertical list.  Also, I'm trying to change the size of the images in the basic parameters, but they're staying the same size.

 

The second is with a k2_content module.  If I have an item with an image, some of the text is placed over the image as if there's not enough padding around it.  Where do I go to edit this?
