Changing caption from description to alt text

I recently updated my nextgen gallery and I am struggling to get it formatted back like it was. Anyways I have my thumbnails showing up in a basic gallery which is fine using the template caption. Which looks like this: https://www.olsonsilver.com/handmade-buckles/ This is basically how it should look except instead of the description below like it is now I would like just the title of the photo to show. Does anyone know where to change this?
