Why do my classifieds button look so crummy?

See at http://perrypulse.com/classifieds-2/

1. Why is there that little text that says, “no categories?”

2. why are there all those little gray useless boxes?

3. Why are those shortcodes showing up in columns?

This has taken forever to figure out even thus far. Help is greatly appreciated. I can’t publish looking like this.
