How to get the voting to show on the pop-ups

I have this page:

https://christianboyce.com/murchison3rdgrade

This is a basic gallery, and the thumbnails show the voting underneath them (as stars). That makes me feel as if I added the code in the right spot. But, when I click on a thumbnail and the bigger version displays, there are no stars to click on.

Using NextGEN Gallery Plug-in Version 2.1.31 and NextGEN Gallery Voting Version 2.7.6.

Thanks for your help.
