Your ranking fields are set differently on the different sheets?
Look at the way it is set up on the Placing table sheet and imitate that on the other sheet. (Table calculation => Advanced, then move everything over to right side except Medal and then set it to calc at level Country restarting every Venue)
Hope that helps,
It works when I filter on one year only.
But if I filter on 2 years the ranking is right for placing table on the right side but it doesn't work on the medal table on the left side.
