DefaultPawn eye height resets on play

I set the camera eye height to 70 in the editor for the Default Pawn and when I hit play this value resets to 0.
When I set the value in play mode, the eye height adjusts instantly.
When I escape play mode the value goes back to 70 where it was before I hit the play button.

Is this a glitch in the default pawn class?
My base move speed doesn’t reset like this.

I am trying to do level test and any help would be appreciated.

Regards, Rigel
