Menu links defaulting with extension "__trashed"

Hello,
I've created a theme using Upfront Builder (active theme) and I'm having trouble updating the menu with the proper directory. After selecting which page/post to associate a menu item and saving, the link then defaults with a strange extension: extraord/about-us__trashed/
