Vector3 array not showing up in inspector!

Hello! This is a strange problem, which exists on my desktop, but not on my laptop. The following script requires a vector3 array to be initialised to store the set of nodes that my spaceship traverses. After many failed attempts, I realised that the array which I initialise in Start() does not show up in the inspector, and subsequently affects future assignments.

The code snippet:

 public Vector3[] vPath2;
 void Start () 
 {
         vPath2 = new Vector3[5];
              //....other code
  }

How it should show up:

How it is showing up:

These screenshots were taken during play mode. The laptop runs 5.0.1f1, the desktop, 5.3.1f, but I dont think that should make a difference.

I don't understand what's going. Wasted a day for this! Any help will be appreciated.

Thanks!
