Display System Field in Test Plan Details Tab

Hello All, 

I'm trying to display the system fields under the Test Plan Details Tab. I have administrator rights and some how when I create a new test, all the system fields are not appearing. 

Only the following files are visible

1. Creation date

2. Designer

3. Priority (user defined)

4. Status

I want to show more system defined fields, such as Path, subject, etc. 

I tried to place the following code under 

Sub Test_MoveTo
On Error Resume Next
Test_Fields.Field("TS_PATH").IsVisible = True

On Error GoTo 0
End Sub

Still the Path Field is not visible under the test plan details tab. 

Kindly help to adivce.
