I thought that was part if the strategy of the game, one possible win is to force in impossible 3-3 on an opponent and claim the victory. It also doesn't seem like yours is a double 3 though, so I'm confused about that.
it is a double 3, diagonally it'll create a free 3 and in creates a row of 3 with one gap, back in gms you could have double 3's if it means blocking 5.
