Can't delete empty folder in Outliner

Hi,

I have a level that has a couple of empty folders in it. Their visible flag (eye) is off and I couldn’t make them visible. Once I delete them by hitting the Delete key on keyboard or through right-click menu, they keep coming back when I reload the level or simple toggle the level’s visibility off/on in the Levels window.

To clarify, I am referring to empty folders in Content Browser but in the World Outliner.

Hey Jason, for some reasons, it worked for me and did not come back. But, UE is so unreal that I might have this issue in the future, but hopefully not. Let’s see what unreal gods decide.
