Can't change e-newsletter template on localhost install.

I am testing out the e-Newsletter plugin on my localhost development server, and I can't choose a different newsletter template. The image with the "Activate" button does not show up.

This drove me crazy until I tried installing it on a live site and it worked fine.

Then I duplicated the live site over to my localhost server and once again I can't change the template.

Everything else works, even the email sends a test from the localhost installation.

Is there something about localhost that keeps the template chooser from working?
