Filter prompt for dojo data grid is improperly formatted

I'm working in Xpages and attempting to create my first dojo data grid. I have a grid of data. However, I think I'm missing a css class somewhere because the column sort options don't look correct and the filter prompt window is way too small, resulting in everything being bunched up and unreadable / unusable. What am I missing?

Here is the source:

You have a bug in your own code :-) Change your reference to the EnhancedGrid CSS files from /esources to /resources.
