BP Enumeration not showing window; not editable

I tried to rename an Enumeration object and after I did, I could no longer edit any enumerations in my whole project. Even creating new enumerations are uneditable. By “uneditable”, I mean that when you double click them, the window comes up but the text box lines and internal window do not show anything. How do I fix this?

Goto “Window” in the menu and click “Enumerators” to show the window again if it somehow gets closed. :\
