Events Plugin Broken after activating "additional fields" extra

I ran in to a problem on a previous test site, tried uninstalling and reinstalling and still had the same issue. Installed a new instance of wordpress and found the problem.

Events Plugin was running fine. I was activating the additional features in the settings of the events plug in, and one I activated "additional fields," the settings page no longer shows all of the additional features that I had previously had the option of activating, I lost the "save" button, and it won't let me add additional fields.

The Attached screen shots show the altered formatting of the page and the lack of save button.
