Bug Bug in Unity Inspector, Doesn't render properly the first sub element of element for a field

Code (CSharp):

1.  
2. public class LevelManager : Monobehaviour
3. {
4. [System.Serializable]
5.     public class LevelObjective {
6.         [SerializeField] List<GameObject> Objective;
7.     }
8.  
9.     [SerializeField] List<LevelObjective> level;
10. }
11.  

create a codee like above and you will see in inspector that it doesn't render the first sub-element properly, It will be overlayed by other elements below the 1st element. Which makes it impossible to work with.

 

It's a really annoying bug.
You can add [NonReorderable] if the order is not important or make a custom inspector to fix this issue. Hopefully the next LTS will fix it, since the fix is already available in the tech stream
