Player not showing under team properly?

When a player joins, I've got a script that changes their TeamColor to the same colour as the 'Flight' team, and sets 'Neutral' to false. Very basic.

game.Players.PlayerAdded:connect(function(Player)
	Player.TeamColor = BrickColor.new("Institutional white")
	Player.Neutral = false
end)

However, it hasn't worked. This keeps happening. The name has only shown up correctly (under the Team) at random times when I test it, and after the one of the Player's Leaderstats values have been changed. Any help is appreciated, and thanks in advance. Also apologies if this is not exactly script-related, I was just unsure.

game.Players.PlayerAdded:connect(function(Player)
	wait(0.25) --It waits for it to load.
   	Player.TeamColor = BrickColor.new("Institutional white")
   	Player.Neutral = false
end)
