I see a discrepancy in the Manager Calendar and the League Schedule I'm in! For instance todays race is scheduled on the 19th of May but in the Manager's Calendar the race took place in the 17th! The next race is scheduled for tomorrow, 20th, but in the Manager's Calendar the date is 18th!
Pedro, I cannot see a problem with the league. This could be an issue with time zones. The race times are all based on gmt. Which time zone are you in?
This is caused when races are postponed in a league, because the race is moved but the calendar is not updated in the same way. This shouldn't be hard to fix, but it will have to wait because it's not urgent, it's a display issue and won't cause problems beyond the calendar.
You will have a new season generated soon and the calendar should be back in sync.
