Captions Not Displaying In Gallery

Relatively new to Montezuma but so far I'm absolutely loving it. Just rolled out a brand new site using it at http://www.killthecan.org/

My question is around the gallery feature. I do a ton of photo sharing for my members and like to caption the photos. It appears that the standard gallery functionality via WordPress (no gallery plugin installed) does not support captioning photos in either the grid view OR when you click on the thumbail to get a larger view.

See http://www.killthecan.org/about-us/b...nd-meet-82012/ as an example. I've verified that all photos in that grid do in fact have alt tags, titles & captions.

Any thoughts on getting the captions to show up both on the grid view as well as on the photo itself would be greatly appreciated.
