visual studio code – Duplicate folder in VSCode file explorer

Please see the picture

Notice the backend folder is shown twice.
Hovering over it shows the same path, and opening it shows the same items, so it is indeed the same folder.

What’s going on here? Why is the same folder shown more than once?
