Ghost Asset - Duplicate map

I am using the Project Launcher window to export a shipping build of my game. For some reason, one of the maps is duplicated (See Image), even though in the Content Browser I only see it once.

I suppose it’s some sort of ghost asset, a redirector or something along those lines. I tried using “Fix up redirectors” and deleting the ‘saved’ and ‘intermediate’ folders but it’s still there.

The build is successful, but when I try moving to the duplicate map, the game throws a “fatal error!” message and crashes.

What can I do? Thank you for the help!!
