gms_team_player_count doesn't count himself player?

Use code on button:

On Click:
gms_team_join ( 2 );

On Draw:
var team0 = gms_team_player_count(1);
var team1 = gms_team_player_count(2);

draw_text(10, 400, team0)
draw_text(10, 430, team1)

Other players are shown, the player on your screen not. Bug or feature and how I can fix this?
