diagonal linefill

Got i hope a simple question for you all , in my foillowing code i have a random diagonal line and i have no idea where it is coming from?
any help would be great thank you in advance 🙂
RoadVerts =[-1,  9, 9,  11, 11, 21, 21, 11, 11, 9,  9,  -1, -1            11, 11, 21, 21, 11, 11, 9,  9,  -1, -1, 9,   9, 11            0,  0,  0,  0,  0,  0,  0,  0,  0,  0,  0,   0, 0            1,  1,  1,  1,  1,  1,  1,  1,  1,  1,  1,   1, 1];fill(RoadVerts(1:1,:),RoadVerts(1:2,:),'w');xlim([0 20])ylim([0 20])zlim([0 5])

% Was: fill(RoadVerts(1:1,:),RoadVerts(1:2,:),'w');fill(RoadVerts(1,:), RoadVerts(2,:), 'w');
