Race postponement error

On Saturday, I chose to postpone the race on the 24th because of Christmas. The race would be held on the 26th. Everything appeared correctly after the new date was chosen and the calendar indicated that the change was successful. But today as I entered the game, no changes were made, so the race I had postponed will normally take place tomorrow. How to fix this error? All League members already have an appointment and the like.
