League Table not sorting

Hi, i just created a league table, assigning all the events to it. Even if the count of the matches played, won and lost is OK, still the league places the ahead team (it’s a Team-vs-Team series) on 2nd place, and losing team on 1st place, but indicating for both “position 0” (Pos 0). The website is https://www.floball.it and the competition is “Test Match Series”
