Error in nation rules

[oregu]

FM22. I try to create a tournament, which includes group stage, where teams play matches only with the teams from another group. There're two groups with five teams. So each team must play 10 games (2 rounds).
I create 10 dates for each game. When i try to test rules, i receive message:

I don't understand why. I tried to use almost every option. I tried to setup date range instead of specific dates. There's no error, but when i load new game, all matches are spreaded across 13 dates.
Can someone help me?

5 teams indeed only need to play 10 games, but..... every round one team does not have a game. So you need to account for that as well.

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.
