Great to know. Yes. I do have the developer plugin. So I could just throw another instance of UNA up on my CPanel, export the menu and then import again in the UNA I want to fix, correct? I am going back to the original default menus anyway so I do not care about preserving anything I have done.
If you don't mind installing another instance of UNA, it's better to reinstall the first one. And then export the original menu before any work within.
