Go to Menu > Manage > Stats/Standing > Stats/Standing Grouping, Player Tab.

Check to see if Player stats have a start and end date. If there is an End Date, the system doesn't add anything after that date into the stats.

*Be careful, when putting a date, it puts 12:00am. Which means that the day of doesn't count.

(Ei: 04/02/2019 12:00AM anything played on April 2nd won't count. Because it stops first thing that morning)

Select the league, Click on Pencil, Advanced and change the date if need be!
