League table is not showing correctly the eventsplayed by each team

Hi everyone
I imported the events (matches) with each club (team) displaying correctly and I can see them on the events tab correctly.
But when I create the League table it does not show the correct number of eventsplayed by each club, neither the wins, draws or losses. Only one or two, when they are supposed to be 4 events played.
I realized that when I go through each event and I open again the clubs (teams) just to re-select them and click update, they are now correctly (+1 eventplayed) but I need to go one event bye one, it takes too much time, considering that they are already selected correctly.
Does somebody know what could be happening? Something on the import file is wrong with the clubs or something on the equation (the equation of events/matches played is eventsplayed). I am talking about soccer.
