Excuse me, i have to explain again.
I create online team tournament. Theres 10 men (5x5). There's no games inside the groups, only against another, so it's no need to include bye-weeks. They play something like that.
R1: g1-1 x g2-1, g1-2 x g2-2, g1-3 x g2-3, g1-4 x g2-4, g1-5 x g2-5.
R2: g1-1 x g2-2, g1-2 x g2-3, g1-3 x g2-4, g1-4 x g2-5, g1-5 x g2-1.
Etc, 10 games for a team, 5x2 against clubs in another group.
But for unknown reason it divides matchday.
