Gameobject names in Hierarchy Panel not showing up.

I’ve cloned a repository from GitHub and opened the project in Unity (Unity 5.4.2).

The name of the game objects in the hierarchy panel are not showing up at all.

However, I believe, names of prefabs are showing up. Anyone know what may be causing this?

I’ve had this happen before, the only way I’ve gotten to fix it is by downloading the exact version of Unity that it was saved in. You should be able to find a file in the Project Settings folder called ProjectVersion.txt that displays the version of Unity used last in the project
