I spent a while looking around and I can’t figure out what the issue is. I’ve activated the Genesis Slider, enabled the menus, and adjusted a lot of settings and nothing changed.
The issue isn’t the Legacy theme as I have switched to another theme and the issue remained. I have no idea what it could be, but there is definitely something on your site/backend that is conflicting with your setup.
Since the Legacy theme isn’t what’s causing the issues, the only thing I can recommend at this point is to uninstall all of your plugins to see if one of them are causing the problem.
