Are you referring to both characters being at the start when the game begins... both the blue cube and the viking guy?
The reason for this is simple... you drop both when the scene begins regardless of which the player chooses.
You will need to either start them off the screen (below ground level) and "spawn" the chosen one at the start point or set them both to invisible at start and set the chosen one to visible when they are selected.
If that is not what you are referring too... please be more specific.
