Issues with Cloned Events in MixPanel Setup for PMs

I am in the process of setting up MixPanel (I am a PM). I set up some custom events, which seemed to then auto-created a cloned event (same name) that doesn't show up in the custom events list, but does show up in the events list. Those cloned events seem to be buggy (not pulling event data for some reason). So then I deleted the custom events to try to clean things up and start over. But the auto-created cloned events are still there, and I don't have a way to delete them. Any thoughts?
